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.

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!!!

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.

Decent Entry-Level Scanner
Easy to use, paired fine with my Android phone. Alerted me to a problem I was unaware of. Great value for someone who’s reluctant to pay their mechanic $100+ to tell them why the “come give us a bunch of money” light has come on again. Saved me the inconvenience of finding time to go to an auto parts store to have them scan for codes. Functionality: see above. Build Quality: seems like a physically solid unit. Looking forward to having it handy when our other vehicles throw us a trick. Helps me know what I’m getting into with my cars, and if I can DIY a fix or have to take it to the mech.
