text: Overall, good build quality, works as a bike pump, and I like the general design. However, it has several minuses that, while individually were just annoyances, cumulatively added up to be a deal killer: - It's single action, so it takes about twice as many strokes to inflate a tire. - The handle doesn't lock when not in use, so you have to secure it tightly to keep it from extending while stored and getting full of crud. - When I checked the pressure gauge against a decent automotive one, the reading was 5 psi low. Not a lot, but when you're shooting for 25 psi, that's a 20% error. - The presta side of the adapter hose does not depress the end of the presta valves on my tires, so the pressure gauge is useless for me anyway. - The strap that came with it was flimsy, and on my first actual ride with it mounted in the bracket, I looked down after a quarter mile to see the frayed remains of the strap and no pump. I'll be buying a replacement of a different brand, but I would easily buy this one again if the above flaws were fixed.
