Review on WOTOW Mini Double Inlet Bike Pump, Portable On Bike Pump Fit Presta And Schrader With Repair Kit, Metal Rasp, Tire Pry Bars, Glueless Tyre Patches For Frame Mounted Road Mountain BMX Gift by Herve Latreche

For $10 I wasn't expecting much, and that was what I got. The pump is functional, but it does a poor job of locking onto the valve stem of my tire. I can hear air hissing out if I don't hold the pump just right. Still, it's able to put air in the tire faster than it comes out, and for something I don't plan on using often, that's acceptable. Definitely don't buy this expecting it to do the job of a floor pump - it's for emergencies only.
