I have the OBDCOM tool. OBDCOM's support is just incredible. They helped me figure out what was wrong with my Jeep on a Sunday afternoon! The tool and software is real easy to use and does alot for the money. Shipping was fast too, I received it in the mail just 2 days after I ordered which really surprised me since I was in CA and they are on the east coast. I have version 2.42 of the software now, they just updated it recently. Very satisfied customer!
