The pressure gauge works perfectly. It's small and the numbers aren't very readable for the visually impaired, but I like it a lot as I often leave it on my back when I'm on gravel or mountain biking to adjust the pressure. Anything bigger would be heavier and less comfortable on the back of the jersey. I also use it in my house. It seems to be as reliable as my floor pump.
