It's good to have it when you need it, rather than need it and don't have it!
Works really well. Great for topping off air pressure. Why spend $3.00 for a couple of PSI's. Good addition to my automotive emergency kit. Quick, easy to use and noise level is minimal.

Really nice inflator
Overall a great buy. It lets you set a certain psi and it automatically shuts off. Also saves the set psi for the next time. The light is decently bright although the carry handle is awkward and I wish that the handle was just different. It's just not a great handle. The inflator airs up a tire fairly quickly, also doesn't vibrate as hard as some of the cheap ones from Walmart. The only problem I had was the 12v plug had somehow overheated and the case had melted and the whole plug had to be replaced. Other than that it's a great unit. Maybe I just got a bad one
