I’ve owned an older version of this pump for probably two decades and the grease and o-ring finally started giving out so I am going to guess this model is about as durable. It is slightly shorter and pumps about the same. It is nice to not need to convert the head to use it with schrader. It works fine on both my long and short presta valves at the low pressures under 25 psi that I run. I would prefer the aluminum cam handle of the older model, but the plastic one seems to be holding up ok so far. This very light, compact pump is all I ever use for pumping mountain bike tires and it is an excellent value. I prefer using an accurate separate releasable pressure gauge at the trail head or even in my pack to having a crappy one on the pump.I’ve been using this exact pump now for more than three years on a variety of tires, mostly presta, and it’s working fine. Highly recommended and required equipment in my book.
