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 Mike Dart

Got the product and tested it. It first it latched on and pumped fine through a handful of pumps on a fully deflated tire. I shouldn't have stopped there. On the trail went to adjust the air pressure and the lock won't stay on so air escaped around the valve and deflated my tire even more. No amount of pumping put any air in the tire. Tested it again at home and the lock won't stay on past about 10psi in the tire. If the lock worked I bet this would be a nice little pump.Update: After reading my review the company contacted me vary quickly and shipped a new pump to me. Have used it to pump a tire all the way up and for small psi adjustments and it was very easy to use. Would highly recommend this product or others by this company, there customer service was fantastic.
