Rubbish

Please don’t waste your money

I'm cool with it

I been using it some atleast 4 years now and it works perfect for what I need it for. The codes are true to the devices knowledge. It found my problems on my 08 gmc Yukon saying #5 coil was bad and after replacing it fired perfect. And it also is showing other codes that I know for a fact need changing but yea ish work good. Also I used It in my brother 2025 Honda and helped others figure their problem out

Software is super easy to use

Was able to connect my OBD2 reader to my iPhone with this app without any drama. The app seems to do what we need and it is very simple to use.
