Very easy to use. We were able to quickly diagnose two (and immediately fix one) check engine issues on my sister's vehicle. The reader did not require any set up, just plug it in to the data port and wait for it to get diagnostics. You get a code and also a description of what the code means, so it's much more understandable than the cryptic error codes a PC gives out. I only had trouble clearing the codes because I did not read the directions closely. When clearing, just put the key in and turn it once but do not start the car. Have not tried the real-time data collection. I really like this reader, and at this price it seems like something every vehicle owner could have on hand.
