If yours broke it broke, but I must say that I was impressed by how solid and well built the fold out thing on mine seemed when I started looking at pumps.
A fellow who posts here at times had his road morph pump shaft break while on his big south America trip, so they can break, like anything I guess . I think all one can go by is having whatever gadget actually in hand to get a real hands on feel for build quality, and then I guess to try to get an idea with online experiences to balance out just how often problems arise vs people with no problems.

I could see with any vertical pump that if you go at with abandon, and there's a slight wobble at the top of the stroke, with enough pressure, it can start up some play that could get worse and worse, possibly leading to a sideways force that would weaken the shaft....or who knows maybe his pump was defective, same as your fold out foot brace.

I felt the topeak felt a little sturdier than the lFILZER similar model, plus it is slightly shorter, which I like.

*** I mistakenly wrote lezyne before instead of Filzer , they are the ones that.don't seem as well made as the topeaks....
