OBD101

So this tool is very reasonably priced, saved me $160 compared to going to shop. Worked great to rewrite BCM in 01 Silverado 1500. Arrived pretty quickly. Why a 4 star? The information, instructions were a little vague. I have some training and experience so okay for me, but maybe not someone with less training and experience.

Unsure

I give it a 3 and that's because what i get it for I haven't been able to see if it works.

Will not connect to my Bluetooth on my phone nor my wife’s phone. Both are Apple iPhones that should work. Tried both my 2018 Silverado and my 2022 Ford F250 and neither worked.
