Freind of mine whos a tech said most of the guys use this because it does everything a SnapOn does at 1/4 the money... well now it's 1/10th the money... I have it and it's amazing! Does all OBDI and OBDII, records data, cable to download and get upgrades each year. Mine came good through 2010 cars 2 years ago... I paid $100 more than what it is today...
