Functionality
This product has been pretty great tool. Gives just as good as any other scan tool I’ve used in the past. This maybe even better than most. Very accurate…. I really like that it has link to search part that need replaced as well as probability of issue that may have to deal with at critical mileage points. I have nothing negative to say about this product durable, reliable & for the low cost it’s a must have tool. Overall great scanner!!!

Easy to use!
Neat little tool and easy to use. It will run a diagnostic test on your vehicle and show the different codes that need attention. The thing I like mostly is you can sync this tool to your phone by downloading a free app and the app will suggest the parts you will need to fix your vehicle! Pretty neat tool at a good price.

Two Devices in One.
This is a nice little device that does all the functions that most of the lower end units do (and let's be honest the lower end units are all pretty much the same except for the shape of the device and the box it comes in) Plus the added functionality of Bluetooth to send data to a phone app. That's much more rare and usually reserved for more expensive units. So, If you've ever wanted to have a Bluetooth reader and a handheld unit together for a better than fair price, this is what you want. The phone app is definitely better than most, but not the best (but considering the price better than what we should get for the $$$), and absolutely usable and I can't complain about it. As for the actual unit, the cable is way too short, display too small and it's nowhere near as large as the photos make it appear (See pic. Laptop mouse used to represent true size). Do I wish it was bigger with a longer cable? Absolutely. Would I buy it again? Absolutely. I'll give it a strong BUY recommendation.

Worth the money
Good device it accurately lets me know when a vehicle passes a smog check and if it has any serious issues depending on the codes, I’ve dropped this product many times and it’s still working perfectly fine, easy to use this is actually the second time I purchase it good investment 🙌🏼

Simple to use OBD2 scanner
This scanner is easy to pair with your phone. It read my codes and I was able to clear the "check engine light. It also will save the condition the powertrain was at when code popped up. It's not the biggest screen, but it does do what was promised.
