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
