Review title: A salvage pump at best Product review: PROS: Very light and very sleek. Gauge on pump. High pressure and high volume settings.CONS: This product comes with little in the way of directions, and is not 100% self-explanatory. I took the pump to my local bike store, and one of the technicians there showed me that you need to place the pump onto the valve and *then* twist it to the "on" position (with the gauge facing the side of the pump that you are using). With the Schraeder valve side, the pump can put out ~30psi at best before air leaks around the O-ring that keeps the valve in place. Considering that it is a chore to get the pump onto the valve in the first place, this is disappointing. This pump will allow you to get enough air in your tire to get home, but do not expect to get ideal (60-80psi in my case) tire pressure using this pump alone.
