Got this for $9 off ebay. Also got a $13 scan program. WiFi to my laptop lets me scan sensors, read codes and reset them. Does some other things I have not tried yet. Works on the Cayman and 98 Chevy truck so far. They say it works on any OBD11 car. Did not really need it but its a fun tool to have if I do. My truck sets an SES light once in a while but it goes away after a few days. Next time I will be prepared.
