Got my dice tool from alibaba.com or something like that.. can't remember exactly what it was but it came from china, other members recommended it. I never got it working, I think my problem was with trying to run xp on my mac. I no longer have the software, the place just sent me a download link that took me to a torrent site when I told them it wasn't working. I believe you can get the software on ebay. The dice tool did light up and communicate with the computer and car in the brief time i got the software kind of working. As far as I know the tool works completely fine. There's no reason for it not to. I paid $130 for the tool and software which I've seen on ebay for about $30.. so I'm asking $65 of the tool. OBO. If for some reason its not working I will accept returns within 7 days of receiving it. PM me thanks
