Accurate
Very helpful and works well. Plugged into my car to figure out what’s the engine light is for. Gave accurate code and got it fixed. The mechanic gave me like 4 different issues do saved a lot of money.
Jackie S. –
Accurate reads!
This scanner diagnostic tool gives accurate reads. And also allows you to clear the code. My check engine light kept coming on. I knew what the problem was before using the scanner and was surprised of it’s accuracy. No more wasting money going to the auto part store to have it read. It’s easy to connect to Bluetooth too.

Useful
Easy to use, informative. Can diagnose a wide range of problems. Although, for one of my cars it gave a full diagnostic, and for the other, certain tests it was unable to run. I’m not sure whether that is due to the device or the vehicle.
Will Phillips –
Super easy to use
This guy is great, download the app and then it’s literally plug and play. It didn’t work at first, but then realized my truck needed a new fuse for the plug, so make sure to check that if it doesn’t work initially. Now I keep it plugged in all the time and can get diagnostic readings whenever I want, not just if it throws a code. 100% recommend.

Great to have
We were happy to buy this product. We have a 06 Scion that finally started having issues after all these years. We bought this to help figure out the codes. We were able to get our tough little Scion up and running the same day. Plus side is it’s small so my husband can just pop this thing in his glove box and it’s always right there when he needs it. We love that it orange so it’s easy to spot when it’s dark outside especially since we live in the country with no lights around. He can easily spot it for quick fixes. Good product, easy to use, and very handy, worth the money.
A. Laguna –
High ROI within weeks
This scanner has paid for itself in more ways than one. First, I was able to scan two vehicles that had CEL on within several weeks. This saved me from going to the auto parts store 15 miles away and having a complimentary scan done each time. Second, I was able to tell my mechanic/dealership exactly what was wrong which let them know I was informed and never once had them try to upsell or tack on to the issues that were found.

Awesomeness

Plug and play precision
The product itself brought me a good deal of confidence when going to look at a car for purchase! It has also confirmed things for me since. I would definition buy again and will continue to use it as needed . The only thing this thing has not been able to do is disclose physical ailments of the car.

Scan Codes and Don’t Get Blindsided!
I bought this to be able to identify what codes show up when a check engine light comes on. I plugged it in and tried it out only to find that the dealership missed a calibration on my car. I’m so glad I got this and saw the code before the dealership can turn around and say it was my fault…
Parker O. –
Plug and Play
Just plug it in and it was recognized by my iPhone, works great and connects to all the cars I have tried so far.
Rafael Rodriguez –
Good for your car
My car had problems and I didn’t know what they were until I bought the scanner reader. Since I received it, I used it in my car. It worked and told me what the problem was… I recommend it so you know what your car has and with that information, you can fix it.

Easy to use
My car broke down and i have no idea what is wrong with it. When i plugged in this diagnostic tool, it was so easy to read the codes and see what errors my car was showing. The app works on multiple car brands too!
Joe –
No more shady business at the car mechanic
Now i’ll be able to know if the mechanics are being truthful or not about the problems in my car. I drive an old Sentra 2015 and makes all noises you can think of for a 10 year old car, but I have always been sure that the engine and everything else has been taken good care of. This obs scanner makes full scan of all the codes that a car can have, it connects to your phone so quickly via Bluetooth and also gives you real time information of what’s going on with the car.Ordering a second one for my wife’s car.

Diagnose issues
I used this on a friend’s car whose check engine light was on. We were able to pinpoint the issue, get it resolved and the car passed inspection. Handy tool. Saved a bunch of money that would have been spent taking it to a shop to be diagnosed. Easily paired with my phone, with downloaded app.

Great for reading check engine light
I bought this because my check engine light came on and i wanted to see what was wrong. I plugged it into the obd2 port and connected it via the app and it was able to scan my car and told me i had a misfire on cylinder 2. I changed the spark plugs and coils and it ran normal again. Its cheap and works good. Much easier than getting it checked at auto zone where is used to go.

This OBD2 Scanner has been a fantastic addition to my car maintenance routine! My check engine light had been on for a while, and instead of going straight to the mechanic, I decided to try this tool. It worked perfectly right out of the box.

Plus the app compatability makes it all the more worthwhile! Highly recommend this product over your usual OBD2 scanner because the app for this one gives you all the info regarding the error codes and saves a ton of time!

Saved Us Big Money!
My son was having trouble with his vehicle and thought it needed a very expensive part but after utilizing this scanner he found out that it was only a sensor of some sort that needed replaced. Boy was he relieved and we were glad that my husband had purchased this scanner which he states, “So easy to use, even I can figure it out”. He’s not the most techy individual. We highly recommend this item.
Henrry Martínez –
Just for general information
Good to have general specs from your car. I was not able to restart the codes tho, will have to study it better.

High quality
I used this OBDII kit on my Toyota Camry, and it works perfectly. It allows you to view various parameters of your car, and if there are any errors, they are displayed in the application. The kit paired with my phone easily, which I appreciated. I think tracking your car’s information is a great feature, as it can help you save money by allowing you to read error codes from home.
Lizzy Surena –
Very convenient
My engine light had been on for quite a while so I bought this and so far it works great! It gives a lot more details than a traditional device with no need for searching what code means what, etc .. It’s a really great device

Good product

Isaac Rivas –
It works
Tested it out on my BMW and its able to capture most of the metrics, however, I wish it could present a scan of all visible codes and just any Check Engine related one. Is very simple and does what it says, but it could benefit by upgrading the app to show more codes from the computer.
Britton Williams –
Great little product
This product had a very simple set up. I was able to complete a diagnostic within 10 minutes of opening package (7 minutes were used finding the OBD port). Scan was accurate as it display exactly what the mechanic told me the following day.
