Review on 🔧 KONNWEI KW850 OBD2 Scanner: Professional Automotive Code Reader & Diagnostic Tool (2021 Update) by Shawn Sims

I am very impressed with this reader. This has already saved me money, as well as issues I thought I needed to deal with. I recently took my car to an auto parts store to have the engine codes read. They said they needed a new battery. Well, as it turns out, when I used this reader, it told me the battery was fine. He also told me that the check engine light was not caused by the knock sensor, as the tech at the dealership told me (to replace would have cost over $1,000) but was actually caused by the EGR sensor, a part that would cost me $1000 $ to replace myself. $50 (and much easier to replace). Obviously not everything that is in the auto parts store is as good as what I bought on Amazon. So, kudos to these guys for selling a really high quality reader. I haven't explored all of the settings on this reader, but I can say it's very well made and has a TON of functionality. Definitely worth buying.
