Review on KONNWEI 【Upgraded】 OBD2 Scanner - Professional Auto Code Reader | Car 🔧 Diagnostic Tool for Check Engine Light | OBD II Car Diagnostic Tool Since 1996 by Justin Woolley

I have an old Ram truck that suddenly had a check engine light on. This isn't the first time this has happened to me and I decided it was time to get my own OBD scanner to diagnose and fix problems with my car. This scanner was very easy to use. To be honest I didn't even open the owner's manual and was able to figure out what my problem was and fix it so the check engine light went away. If you can work with a smartphone, you can use tbiz, it's that simple. It also tests your battery and comes in a nice carrying case.
