No. The tube deflates slowly. Possible to ride for ~5 km or so.

Yes, seems like so. Given what other gentlemen answered, it's 80% user error. Don't like the pump, though, it's hard to not moving back and forth while pumping. The head sits on the valve loosely, thus needs to be supported by left hand.
