Very excited to have this arrive. Great price on a OBD II scanner. This scanner can do most options I need to do like: reset the check engine light, give me the codes that my car produced, but what is great is that it also can give live data of the what is happening with your car. This device can diagnose your car once you basically break even considering the dealers diagnosis costs. The local dealer wanted $100 for an hour of diagnoses that that would provide the same results I could produce in my driveway in about 10 minutes. I recommend this OBD 2 scanner to anyone looking to find out why their check engine light is on! Excellent buy.
