used it for few times now. gives me information on few things like how engine works but still need to figure out how to use it fully and I am not a car pro to say. I bought this to find errors in my car, so far haven't had any engine light come on, so don't know if it'll give me correct codes. If it does, it is a great buy. I just don't want my dealership to charge me $125 to just read the codes and tell me what is wrong without even fixing it like they did about a 6 moths ago. So it will be nice to see if this works.
