“Didnt expect to have to lay additional money to get the app on my phone but at like 5$ i didnt mind too much. Got a basic fault code on my car a wk later and managed to scan, clear and fix the issue easily which meant this thing already paid for itself! Super simple to use for scanning and setup and give basic engine informarion. More info would be good such as boost pressure, fuel pressure etc but for the basic operator its perfect.”
