I bought three, based on the ads (rough looking guy identifies himself as a mechanic). Hi, I'm Rocky Mechanic...blah blah blah, how his friend said...he tried it...blah blah blah, and holy molly, it does everything my 12 thousand dollar pro device does. Or the one where he decided to check it for himself, plugs it in and discovers his gas cap wasn't tightened. Dramatically opens the gas door and tightens cap...problem solved. Yeah, BULL! Before you even think about it, do what I SHOULD have done...go to Google or the App Store and ask for the app. You have a choice! Choice of what? Pay $59.99 for a year's subscription (you have that many lights?) OR pay $7.99 a month. Hmmm? Three units discount brings it to $39.81 each. PLUS $7.99 MONTH (OR FOR ONE USE, IF YOU'RE NOT to quick with math). You guys should be kicked off campus! Of course, if you refund my purchase price, I'll call it even. Oh, no, not quite, I need the freight back to your dorm.
Bottom Line: No, I would not recommend this to a friend
