Just a personal note on the accuracy of the gauge ....

I have two road morphs with the little in-line gauge (there is a different model with a dial gauge, also) and I checked the accuracy of both pumps a bunch of times when I first got them. When checked against an expensive dial gauge, both pumps were never more than 5psi off. I am using them in the 90-110psi range. Great little pumps. I got tired of moving the one pump between bikes all the time so I bought a 2nd. If I can get within 5psi out on the road, that's plenty close enough for me. Again, that's just my experience.

P.S. After many years of riding and many frame and mini pumps, this is the first one that I did not hate using.
