Definitely worth the money. You get what you pay for. It helped me a lot with fixing my Octavia by giving me precise DTC and probably saved me a lot of money because I was able to fix the car myself. For those who are not happy with the device and app you should buy professional diagnostic tool. The only thing that's bother me is that I'm unable to do selected scan. But this one is enough for average car owner who cares about his car. Well done TOPDON!

works well at diagnosing, but if you don't close the app afterwards or or stop it. it interferes with Bluetooth connectivity and causes an issue where you cannot enter passcodes for Bluetooth items and can be very frustrating. took me nearly a month to work out what was doing it

What the app is designed to do, it does it very well. Considering the number of vehicle systems manufacturers have, this does very well on my Mercedes and my Smart car. Obviously you're not going to get technical specialist options but sensors, DTC s and Live data all help with diagnostics. Service reset and DPF activation are the most complicated things I need and that's great as I self service my cars. Also provides peace of mind that if you need a mechanic, you can describe the problems.
