Query: Bent on first use

I thought this was a great idea for a bike tire, knowing I had at least 2 bikes that needed pumped up, I picked it up. It worked well on the first tire, I went to pump the second tire and it bent and the rubber pad broke off. I was able to bend it back enough (with my hands - to show you how weak it is) to put it back in the box until I return it. It would have been a great pump had it not been cheaply made.
