Klymit electric pump - Klymit USB Rechargeable Pump

First of all the nozzle attachment would not go on! It seem too small to fit over the attachment area. I tried it on the other side for the deflation and that went on fairly easily. I kept working at it and it finally went on. However, it didn't seem to pump up the sleeping pad very full. I kept putting more air in, didn't seem to make a difference. Maybe it was the sleeping pad that was the issue not the pump. The whole experience with these sleeping pads/ pump and CampSaver/ Optics Planet has been very disappointing. Sorry, just being honest here.
