Foremost, I smack the beegeebus out of my knuckles when I use this thing. It really ought to stop the stroke high enough that someone with normal-sized hands doesn't have this hassle. (seriously, my glove size is M across the board). I end up having to forgo the flip-out handle feature and move my hand in-line with the barrel. Also, I have some minor issues with this chuck grabbing valve stems, but it eventually gets there and doesn't leak or let go once it does. The flip-out cleat is not locking, doesn't really brace the unit, and is generally worthless. The gauge (almost requisite for road tire psi) is helpful and accurate.I wish I had bought a Lezyne. If it were not because I use frame pumps so infrequently, I would.
