I have had one air chuck fail and blow out an o-ring around the bleed button, and it took forever and asking twice to get another one from Lezyne. Also, I can't use it on wheels with valve extenders. The Joe Blow pump head kind of sucks. It's more difficult to engage than the Specialized pump head, especially over unusual shapes like valve extenders. The pin that hinges the lever falls out the side on mine. Also, the pressure gauge reads about 10 psi higher than reality. The Specialized pump has none of these problems. The pump head engages quickly and easily over standard presta, schrader, valve extenders, whatever. The gauge is accurate to within 5 psi. All pumps are adequate with respect to the volume they output per stroke. The lezyne gauge is accurate to with 5 psi. I don't care too much about built to last. It doesn't bother me to buy a $50 pump every 8 years or so.
