If I bought a hammer that occasionally instead of striking and driving the nail instead turned itself back-to-front and clawed the wood, I'd return it because it's broken. The how or why it does it is immaterial. It's a tool. If it doesn't perform it's task, it's very Reason for Being, then it's worthless to me. If you tolerate broken tools, that's fine, more power to you. I don't. If shit doesn't work it goes in the bin.
