Only tried it out once but was amazed at how the feedback pressure of the pump remains constant as the psi in the tire increases. I have tried other hand pumps and as the tire reached recomended psi it became increasingly difficult to pump. So far I have not noticed that with this. Mounts easily and brilliantly on the side of the bottle cage allowing you to still use it and looks great. Seems a little on the delicate side, when I first had it in my hands I thought I might break it, but so far it has held up.
