I've had this for about a year and a half now and like the idea of checking the pressure when inflating - I'm usually clumsy with valves and will probably lose as much air as much I pump between the pressure gauge and the filler. I also like the pressure release button when overinflating (fairly common on small tires). However, I would like a few annoyances to be addressed. 1) Replacing the battery is a nuisance. You'll have to pull the rubber cover off and wrestle with it to put the new battery in. The battery seems to last a while, so it's just a minor annoyance. 2) The included quick release lets a lot of air through. I wanted to replace the nipple, I have many of these on 1/4"NPT and 1/8"NPT. It was a weird parallel thread that was somewhere in the middle, so I got stuck on the leaks. This is a significant rush on behalf of the company which hopefully has been resolved. EDIT: I upped to 4 stars, apparently the quick shutdown I had was the source of the leaks; I replaced it and it no longer drips.
