Sette Air 2 ST-020AG Dual 2-Stage Alloy with Gauge Pump
The Sette ST-020AG 1-way Mini Pump has a patented dual piston 2-stage mechanism that will allow you to pump with the flick of a switch. It has an extremely durable Alloy body provides optimal protection. The dual valve head permits you to use it on Presta or Schrader without having to switch out any parts. The Sette ST-020AG also comes with a 1" gauge that will ensure you get the exact desired pressure.
The valve on the back that switches between high and low volume is sketchy. Works sometimes other times it would feel disconnected and not pump any air out the head. When it works its good. I ended up tossing it at the garbage can in frustration. If its not reliable it makes no sense to keep.
