Review on EDIAG Car OBD2 Scanner YA-101 Code Reader for Check Engine Light,O2 Sensor,EVAP Test, On-Board Monitor Test,Smog Check,Diagnostic Scan Tool - OBD2 Protocol Car Compatibility Since 1996 by Joel Norfork

I recently received this product to test and compare with my current OBDII scanner. I have a Launch X431 CReader V+. In terms of value, this model is much faster in determining which protocol to use. It does everything it promises and more than CReader V+. VIN search, battery voltage, EVAP and O2 also work. Live data and still images are essential when trying to diagnose a problem. Very easy to use and the button gives a positive click when pressed. With this model you get more for your money. This is a good entry-level or basic OBDII scanner that I would recommend to anyone, especially if you live in a state that does SMOG checks.
