ROTTAY AD310 Classic Enhanced Universal OBD II Scanner Car Engine Fault Code Reader CAN Diagnostic Scan Tool, Read and Clear Error Codes for 1996 or Newer OBD2 Protocol Vehicle (Black)

Simple tool without all the complexity of more complete and expensive tools.

Great product, fantastic price, works well and easy to use.

Reasonable price fast delivery careful packaging and accurate description!

It was very easy to use. The check engine light was on and when I plugged the reader in it told me exactly what the code was and it was very easy to reset.

It's great to have it on hand.

It reads codes easily and will reset your check engine light. It does what it says and does it for very little money. If you have a car with an OBD2 port, you should get one of these. It can save you a lot of money and give you peace of mind. It's easy to research what the common solutions are for simple codes.

EZ 2 can be used even by a novice hobby mechanic.

Very simple and easy to use!

Great device. Easy to use. Works as expected.

It works well when you need it.

I liked the product, the ease of ordering and the price was fair.

An excellent device that can read and clear engine codes, turn off the check engine light, and display real time data. It's easy, fast, and accurate.

Works as expected, check engine light was indicating I was having misfires.

It is easy to use for my first scanner, I recommend it 100%

I bought this product because my car's check engine light came on and I had no idea why. It arrived within 24 hours and was very easy to use. I don't know or understand the codes it provides, but a simple Google search solved that problem. 10/10! I would definitely recommend it!

It tells you what's wrong so you don't have to look up codes.

It is easy to erase the codes

Easy to read and use. I would buy it again.

Works wonders with many more screens than most!

was really annoyed with the wireless OBD I tried to use with my Android phone. I decided to buy this one instead. It diagnosed my Series 3 without any issues. No more issues with apps or syncing.

My car had a "Check Engine" alert, I connected the Scanner and it gave me a code, it also gave me the option to delete the code, I deleted the code, all of this took me about two minutes, I drove all day and the "Check Engine" alert has not returned, I can now take my car to the Smog Check.

Works like a charm. Got my car codes and made my life easier.

Works as described. It had a connection problem error at first, but I wiggled the OBD connector a bit and it ended up working fine. It's probably a loose cable.

Does exactly what I want for the price.

Works perfectly. Easy to use. Codes are displayed clearly.

Great price for an easy to use scan tool

Just as advertised and better, excellent value for money.

Ideal for simple auto diagnostics.

Used and was able to decode engine failure.

Very good price, works very well. I like it a lot.

Good unit for the money.

This product was easy to operate. I liked that it was digital and easy to read. It told me which codes I needed to work on to correct them so I could pass the emissions test. Great product and very accurate.

Works on a nearly decade old Honda…gets the engine ignition code and erases it from the dash

I bought one for myself and my daughter likes it so I bought her one.

Everyone should have one. It's very easy to use and can clear codes if you're stuck on the road. My check engine light came on for a diesel particulate sensor and it went into limp mode with a top speed of 10 mph. I was able to clear the code and drive normally to get home and get it fixed. In limp mode it would have been a 3 hour Dr.

Received quickly, excellent packaging. As described.

It's a good piece of equipment! It works as it should, thank you very much!

bought this for my husband. He thanks me because it's great! He no longer has to run to the shop to get his vehicles hooked up and figure out what's wrong. The device is well built and the screen size is easy to read. He likes how easy the connectivity is, the screen size is easy to read, and the information is accurate.

All the codes came up and even gave me a better idea of where to start looking on my car. It helped me get my car running again.

Very easy to use and has basic functions. Nice to have in the truck.

It works well and displays a lot of information.

I tested the Range Rover and the Kia Soul without any problem.

Our daughter's car had the check engine light on so we purchased this reader and it worked right away. We had used other readers before but they were a bit cumbersome as they needed to connect to the internet etc. This reader did not. Once we plugged it into the car portal and started the engine you can scroll through the different options it worked right away. We couldn't be happier with this reader!

I just received the scan tool and it arrived in excellent condition, I will write another review once I can test the product and see if it works well.

I wish it was more descriptive of the problem. Otherwise it's pretty good.

This code reader is worth buying…it is affordable and shows the codes…I borrowed one from some neighbors who got me one and this one seemed good and was worth the price.

Easy to use. Probably the best scanner I've ever used. And easy to read.

Did the job, arrived quickly.

I purchased this item to check my codes and repair my Traverse. I was able to check and clear codes and then ran the car again to see if the same codes would appear. They did so I purchased the part, replaced it and cleared the code again. No codes appeared again. This is an excellent tool and very easy to use for the price.

used it to find out if the mechanic gave me a correct answer, excellent

Great price, works better than most of the more expensive brands.

I bought this product when I was having trouble with my truck. It works great and is very easy to use. It tells you what the problem is and I have no complaints.

Nothing special is going to happen with this money. However, this tool reads codes and erases the cods… perfect for the money.

had a problem with my car shaking like it was bouncing. I couldn't drive faster than 25km/h. I bought this product to see if I could get a code. I did and after googling it the problem was a mass air flow sensor. I cleaned the sensor and it stopped shaking. I was told by a Nissan mechanic before that I would have to pay for a diagnostic which was about 100 dollars. This saved me a fortune. Easy to read display. Easy to use. And it's detailed information. You just have to google the meanings. Don't trust the book that comes with it. It's confusing. Just google it. I used it on my mom's car that was having problems and when I took it in for service. I didn't say anything about it. The mechanic mentioned the exact same code/problem as he told me this. So you can be honest with mechanics with this.

It saves me from having to go to the parts store every time I'm working on my stuff.

It fulfills its function and has different configurations

It's very handy to have the reset button for when the check engine light comes on intermittently. I quickly looked up the code online to confirm it's nothing serious and the light went off.

Easy to use. Works great. Fast delivery.

It is a good quality scanner, easy to use and with a good price. It eliminates the doubts when diagnosing engine codes.

Good quality and reasonable price. It met expectations.

To check engine functions and problems.

Definitely a great choice for the price and very easy to use, they told me immediately what the code was, I really liked it, it's a great product.

I ordered this to read codes on my 4Runner and it works great, very fast and is a great price!

Simple and easy to use setup. Very useful when looking for used cars.

A very inexpensive way to check codes for DIYers. It's better than going to AutoZone or the mechanic, but you can do it right there in your driveway.

I followed the simple instructions and identified the cause of the check engine light in just a few minutes.

The scanner is fast and easy to use. I have used it once and was very impressed.

It worked great, gave me the check engine codes, I googled them and found out all I needed was to tighten the gas cap. Best 30 I spent in a long time! : Now I can get my car codes at any time and I know if I can get it fixed or if it's a job for professionals. I love it!

It worked exactly as expected and didn't feel cheap to me. It hooked up very easily and is very easy to use. It reads my codes perfectly, allowed me to clear them very easily and also provides live data while the car is running. I used it to turn off a check engine light for faulty O2 sensors. The live data allowed me to see what the problem was and that the voltage wasn't reading correctly. I highly recommend it and would definitely buy it again.

Does an amazing job for the price.

It's not the high end product, but it's enough for most people who want to know what's wrong with their car with a simple diagnosis. Amazing price!!!

Easy to use, worked well.

While I don't currently have any issues with the check engine light being on, I did plug this device in and cycle through the various screens pretty easily. I don't understand all of the responses, but I got it mainly to capture any codes that might pop up so I at least know what I'm dealing with. I'm glad I have this for those unexpected moments, but hopefully it won't happen anytime soon.

Excellent scanner and easy to use. Reads and identifies codes and erases them. Perfect. Compact and with easy connectivity. No technical support needed because it works well. Simple frequency readings.

Get one and save money

This article worked very well and allowed me to fix all the problems with my vehicle.

Everything mentioned in the description of this product it does. I was able to easily connect it to my truck and it explains what you need to do on the device. I highly recommend this product to help you check and clear codes as needed to improve your vehicle.

The product is very easy to use and affordable. It reads codes and clears faulty check engine lights. Do it yourself!

I'm not a mechanic, but I have a small leak that no one can find. That's why I have a check engine light that uses more gas when it's on. So I clear the code every now and then when the light comes on. I like being able to scan everything.

No problem with this. It does what it promises so far. It extracts and displays codes and also allows you to erase them. It displays live data. It seems to work as per the price it claims. It is smaller than I expected but the side effects did not affect its operation.

The device is handy and easy to use. I also bought the case, which is very useful. It worked well on my Ford F150 and my BMW 5 Series.

Impossible to beat for the money.

It starts up almost instantly and can read codes on most cars in less than 20 seconds.

Cheap and simple code scanner. Easy to use, small, easy to carry or store. I haven't used all of its features. I have a high mileage car that has an annoying code that pops up from time to time. When the light comes on, I can't use the cruise control feature. This is a simple way to clear the code and still use the cruise control.

Very easy and pleasant to use in my car.

Used in a personal vehicle. Easy to plug and play. Saved me a trip to Macan and money.

Helped to read and remove all errors from the car. Suitable for home use.

There are no problems with the product.

I used the product for an undetected misfire on the vehicle… The misfire code was displayed to correct the engine misfire.

Worked as advertised right out of the box. Easy to use. Instructions could be better, but they are fine.

I cleared my P0420, monitored the O2 sensors in real time, and confirmed it was ready for inspection once the monitors were set up. Great little tool

It does what it promises, it detects the codes when the light is on.

I turned off the check engine light

The OBD II scanner was easy to use and allowed me to know what was going on with the vehicle. It was very nice to have on hand.

For DIYers, it's great. It informs you about the codes and either eases your anxiety if it turns out to be a cheap fix or increases your fear when you find out the job will cost three times what you expected. It's better than paying a mechanic to charge you for the same thing. Get one even if you're not mechanically inclined so you can be informed.

As good as the 100,000 scanners on the market

bought this to diagnose an issue with my truck. It worked fine, but the vehicle would not report any errors. It turned out to be a trailer transmission error and just needed a clean and filter. The unit worked fine, but the car would not report the error.

The product works like a charm and I was able to remove a code from the system. This product really works.

Best value for money if you are looking for an affordable OBDII code reader.

Quick and easy. Plugged it in, read the code, erased it and that's it! Highly recommended for anyone looking to save money at the mechanic!

It works as it should, it's easy to use and even a blind monkey could read codes.

I connected this product and was given the codes quickly and clearly. It is a great product for the price.

What an amazing little machine. I gave the first one to my friend. These are great, especially for the price. I love it.

Very good quality!!! I would definitely recommend this to family and friends. Great price!!!

Reset those annoying check engine light warnings yourself! It's worth every penny.

I was able to easily read and clear a pesky engine code

Product worthy of 5 stars for its: price, quality and usefulness. If you are looking for a second hand car or you are dedicated to selling cars, here is what you were looking for. It is a product that will save you a lot of money since it has the function of diagnosing the internal problems that each vehicle may have in the system. You can also see in real time the behavior of each sensor of the vehicle among other utilities.

I read my problem, it was just a 02 sensor, I ordered the part, installed it, and the problem was solved. It's good to know what the problem is, so if you take it to the shop you know, and the shop won't try to charge you more money for something that doesn't need replacing.

The other day my wife's battery died which triggered a couple of codes. I purchased this product because it had a lot of good reviews and was very affordable. I was able to read and clear the codes on all 3 computers that were due to low battery voltage. Works exactly as described and easy to use!

My husband likes it

It works perfectly and is very useful for scanning codes and monitoring emissions status and checking when the vehicle is ready after repairs.

So far it works as advertised. I only used it once, but it gave me the information I needed.

It worked great. I used it on my car before visiting the shop.

It does what it says. It's fast and easy to use. It's certainly limited in functionality, but it works well for pulling and clearing trouble codes so they can be looked up online. The strict OBD2 connection saves you from having to deal with complicated Bluetooth and WIFI connections and speeds up access to codes and monitor data. This is certainly not a good choice for advanced troubleshooting. It only works well for occasional resets and for those who want to get a feel for what's going on with their vehicle.

Worked perfectly. Easy to use.

Works great, no issues, has all the basic functions. It's definitely an entry level code reader, but great and easy to use.

Easy to use when a light code appears.

Works great and is very good value for money, I would have paid double the price.

Everyone needs one of these in their car.

I have a traction control and ABS light on due to a bad bearing… it doesn't even detect it.

My husband was impressed with the reading.

They work great for the price. The first one I bought worked so well that I bought an additional one to keep on an older vehicle I have on another property.

Works well in parallel.

I have a European car and it worked. I tried it on a Korean AR and it worked half as well. Works well for fixing some simple issues. Great tool for the price.

Easy to use, cheap.

It helped me solve my problem.

Easy to use, works perfectly.

have only used this scanner once, but it quickly synced with my Bullitt Mustang and gave me a reading of the check engine light. It is very light to handle and compact to store. Highly recommended.

This inexpensive little ODB meter works great. It has saved me several trips to the auto shop.

Great value for money. My main interest was in reading the code, which was listed with a description so I didn't have to look it up. I was also able to turn off the error light. It will reappear if the problem occurs again, which it hasn't. There are other features on this unit that I haven't explored. It's convenient and easy to read.

honestly think everyone should have one of these for their vehicles. As a woman and with an older car, I often find myself in the shop with no idea if the mechanic is trying to make a quick buck. Now I can be more confident and speak for myself.

Works fine on Dodge truck. Cleared codes and easy to read.

This scanner is very easy and simple to use, it's basically plug and play. For the price and the convenience of not having to go to a parts store or mechanic, it's well worth the money. I was able to diagnose my truck and quickly figure out what was wrong with the code I was given. By doing a little research on the code, I found out I could replace the parts myself and save money.

This is a must have tool. Easy to use and very practical.

It works perfectly, it's easy to use, it looks very good quality, and it arrived very quickly.

Amazing product and great price. Loved having this on hand when buying or selling a car.

It's very easy to plug and play and you see results instantly. It probably does more than I use it for, but when the check engine light comes on on one of my vehicles, I plug it in, select the car, and ask for the codes. It's that easy. Great value for the money.

Everything meets my expectations!

It's very easy to use. I was able to instantly determine that the check engine light was due to a small evaporator leak, which can be caused by a loose or cracked gas cap washer. I was also able to clear the code and turn off the check engine light warning without having to take the car to a shop.

It works great and is easy to use, especially for non mechanics.

It was very easy to use, I read the codes very quickly and was able to get started from there.

My washing machine pump broke down. I bought this pump to replace the faulty one. Half an hour later it was working. I recommend it.

The AD310 is an inexpensive and easy to use code reader. It extracts a large number of PIDs and displays many of them in graph form. My tool has one small problem: when you select a parameter to graph, it displays the next one in the list. This isn't a big problem once you figure it out.

It doesn't get any easier than this! If you can plug things in, follow simple instructions, and do quick Google searches, then this is for you. It's lightweight and pretty sturdy for the price. All of the codes that came up were pretty accurate for the problem at hand. I've used it on several car models, from 05 to 23, and they've all been compatible. I would definitely recommend this to anyone who owns a car.

This diagnostic tool worked very well in determining the problem with my vehicle.

I am not a professional mechanic. This article is perfect for me and very easy to understand.

Great scanner at an amazing price!

This device allowed me to directly find out what was wrong with the car, allowing me to fix it before it got worse.

Worked great. Helped determine the problem. Reset the code.

I used it on the UTV to check and clear codes. Works great!

It worked perfectly. The engine light would occasionally come on due to the age of the truck. I plugged it in and the error code came up but I cleared it. It's fantastic

Works great and shows the codes on my car when a light comes on and is easy to read.

Everyone received one as a gift!

It works fine for its intended purpose. I will be returning it as I need a scan tool with more advanced features.

need one that is easy to use and informative. This one works great and I can get helpful error codes that I can google. I can reset the engine control from there. Highly recommended

I only returned it because I needed something mounted on the dash.

just needed to read codes and get some basic information about my car. This worked and didn't cause me any confusion. It also helped me a lot when I was looking at used cars I was able to see deleted codes and problems that sellers weren't disclosing. It worked easily with the OBDII port. I totally recommend it if you just need a basic reader.

Good investment. Very affordable. No battery needed.

Easy to use. I bought this for my 2002 GMC and my 2006 Tahoe, which love to generate DTC codes. It reads almost any common code.

Cheap and works well!

I was a bit skeptical when I received this product because it is so small. But the good thing is that you can take it anywhere. I tested it on three different cars and it is very easy to use. If you are into cars and want to start diagnosing them for any engine problems, this is a good place to start before you buy bigger models. This will just tell you what the problem is, give you a code and also reset said code. Nothing else. Great value for money!

still call it my ODB reader, it was able to read my error codes and reset it successfully. It looks much better than my old device.

Easy to use, just plug it into the port, no batteries needed.

Very easy to use and very user friendly. I was able to diagnose my son's car problem when Auto Zone couldn't.

This is an excellent OBD reader. It allows you to monitor all of the electronic components in your car while it is running and displays the codes with the description so you don't have to look up the code number. I have checked a couple of codes I got online to make sure the description was correct and it was always accurate. I highly recommend it.

Easy to use. I just needed to clear the error code for a common problem that isn't actually a problem on a Jeep Wrangler that causes the check engine light to come on. It worked fine. Unfortunately, 10 miles later the light came back on. But I'll keep it because it's a great value for the money.

I liked the fast shipping and it was as described.

It is an excellent product, easy to use and very useful. It includes many codes and gives you a brief description of the problem.

It works very well but not for my vehicle but for my friends' vehicle it is excellent and easy

It's a simple piece of equipment that tells you the codes and allows you to erase them. It's nothing like any other professional scan tool, however, I like to keep this cheap one in my car and it works great.

It did its job, although there aren't many instructions. It's easier to remove than when I used another model. The price was fair and so far so good.

I ordered it, received it the same day and it works.

I needed to check a code so I could perform the emissions test on my car. I found the problem with the code that was presented, got a new temperature sensor, reset the code, and passed the emissions test. It's nice to have whenever I need it.

I mainly use it to check car codes. It does the job at a good price.

I like everything about it

With an older car, it's nice to have a code reader so I don't have to constantly go to the shop to get told what's wrong. It's a nice device to have on hand!

Good devices, good software, does its job, good price. I recommend this OBD scanner AA plus

My husband loved it. He said it really helped him find out what was wrong with the car.

Good quality tool for reading trouble codes and being able to clear them if desired. Works great!

I recommend it easy to use

It works as it should!!!

I'm basic but I work

Hands down the best OBD2 reader in this price range or close to it. I have 4 of them exaggerated, I know and they all work better than any Bluetooth OBD2 reader or OBD2 readers from Autozone or auto parts stores that are twice the price. If you are on the fence about buying this OBD2 reader, do it! You will NOT regret it.

Helped me read and clear the code after the repair. Saved me a lot. Great product, especially for the price.

It worked perfectly. It did what I needed and for much less money than other similar testers. Very satisfied.

It does its job. For the price, you can't go wrong.

He helped me buy a used car.

It's easy to use. Reads codes. Erases codes.

I bought this to read my check engine light code. It was pretty simple to plug it in and get the reading. The instruction manual wasn't much bigger than a postage stamp so get out your magnifying glass. The instructions were a little complicated but so far I got everything I needed. It works and was very quick. It's a handy tool.

It was very easy and comfortable to use, even for a first time user.

was able to plug it in and get diagnostics without reading any instructions. It's not the most straightforward user interface, but it should be straightforward for anyone who has used a code reader before.
