I bought this little guy to inflate tires on my two bikes. It works perfectly. I especially like the set-it & forget-it design. Simply hook it to your valve stem. Once on the stem, it generates a digital reading of your current PSI. Then enter the desired pressure, press start and it starts pressurizing and counts up as they're inflating. Once the target is reached, it shuts-off automatically. What could be easier. BUY IT!

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
