Bests & Worsts Reviews from Amazon

Works great. My 2010 Silverado tripped a code on the engine. This little device told me I had an air leak, likely from my gas cap. Sure enough, I replaced the gas cap, reset the error code and that took care of it. At this price, every backyard mechanic, or anyone with a car should have one or know who has one. At this price point, it's a great bargain. One last thing, it does not just give you a code like some do, it tells you what the code means in English. Nice!
