Actron CP9175 nice scanner

Does what it's supposed to do. Seems well made. Probably could get by with a less expensive model. I used it to diagnose an SES message on my 2003 GMC Sonoma 4.3. O2 sensor failure according to the code generated. Bought a new sensor at AutoZone and installed. Pretty much broke even cost-wise from what a shop would charge. Will come in handy next time the SES light comes on.
