I needed this tool to troubleshoot OBD2 codes in multiple cars. The price was right and it had all of the features I needed for my wifes 2014 Hyundai Sonata. The menus are clearly organized and easy to understand. The green backlit screen is extremely easy to read, even in direct sunlight. The unit has live data monitoring capability which is also very useful. With only 4 buttons it is very easy and intuitive to use. The built in OBD code lookup database is a really nice touch. You can enter any code and get a full description right from the menu, which has already come in handy multiple times. I would highly recommend this unit for a compact tool to leave in your car and instantly troubleshoot problems!

I bought it to just see an alerting code so I would know whether I was being told the truth when I went to a mechanic, and also to have in the car if stranded/broke down. This model plugged in easily, powered right up, and has a menu that is very easy to just see all options available and explore safely, so even if you don't know a lot about cars it can still be understood well enough to find the error code. As a bonus, I cleared the error code using the Konnwei 310, and the code has not returned. So easy, even I could do it. Now it's in the car as part of my road hazard kit.

Sadly this product cant run diagnostics i.e read Error codes in Fiat models. Other functions like live data works seamlessly.

Excellent product works as expected. Total value for money at this price point. Kudos to the manufacturing team.
