Dear Mr. Cooper, I was glad to hear that your zephal double shot was a piece of junk. At least I know that it wasn't just my zephal double shot which sucked - worthless.

It didn't fit the valve (too tight) and it didn't inflate well when it finally went on.

I actually ended up tearing the valve right off of a new tube trying to get the zephal pump off.

Maybe there was some special way to use the pump, but it didn't have any instructions in/on the box or the pump.

Whew! That felt good.
