Pump works well and delivers the pressure. Thankfully it isn't needed much, so durability remains unknown. Nozzle plug fits poorly, doesn't stay plugged in for long, so is pretty useless, which is a bit annoying. Holder fits under the water bottle cage well and holds the pump securely, though the strap is a little cumbersome. A little better design here and with the plug would be big improvements.
This is a great pump - small, but easy to use and sturdy. It fills my 29 x 2.8 tires with ease.
Looks higher quality than my Crankbros pump that fell apart after 5 years. Hopefully that first impression holds up!
