Review title: Incredibly frustrating
Product review: The first problem with this pump is that while it can be used on presta and schraeder valves, they've marked it so it's never clear when the selector at the top is in the correct position for the type of valve. It's as if they didn't contemplate what would be convenient for the user. The second problem, is that it's hard to get a secure attachment to the valve. And the third problem is that the pump doesn't give you any leverage. So this pump can take you 20 minutes to do what another pump can do in 30 seconds. A poorly conceived tool.
