Great concept! Has everything that
"Great concept! Has everything that you need and it fits compactly. I love that the head of the pump also acts as a CO2 valve. One question though: why would you make the tool needed to unscrew it from the pump larger than what is included in the multitool? Are you supposed to loosen it enough so that it can be undone with one’s hand? Or are you supposed to carry an extra tool?"
