Smal, light, remarkably high volume, easy to use

None

My racing team used to beg to use mine on the trail as all fo their pumps suck. It has since been teh required team pump for tehlast 2 years. Good fit, never fails, works quickly, weighs nothing.

Without a doubt the best bang for buck pump value put there..

I have hated every mini-pump I have used in the last 25 years.

pumps well with schrader valves

ruins presta valves

I got this pump when I had a 26-er with schrader valves. I was happy with it. Now I have a 29-er and am forced to use presta tubes (unless I decide to mess with the rim hole). This pump bends and/or breaks the fragile little thingies (what are they called anyway) that stick out of the presta valve when removing the pump. Already ruined 3 tubes so I'm getting rid of this thing!
