I have the same 8 of these pumps purchased, among other things for our sales force. These have now been around for a few weeks in daily use to inflate the small World Cup footballs on site and to hand over to our customers as a promotional gift. So far I have not received any negative feedback that a pump is faulty or the handling is bad. And that would definiv our colleagues working in the field of the case if it would be so ;-) Our Ballpumpe here in the office makes yet also an impeccable impression. We are very satisfied!
