it works just like you'd expect

it works just like you'd expect. my only complaint is that I cant use data and the ODB2 reader at the same time because it can only connect to iphone though wifi. Stinks if you are tying to search directions and use it at the same time. Its a pretty big annoyance for me. But it works so well at everything else and the price it great, so I give it 4 stars. I bought it because my temp gauge stopped working. It for sure saved me in the Californian High desert during the summer. My car started to overheat and I was able catch it before damage was done.
