When these first hit the market in Home Depot stores, I grabbed a bunch in every size. Many years later, I have seen many imposters of different designs and colors, and I suppose they all work equally well. Bottom line is it caught on big time so I must not be the only one using them. Not the only musician, either because I saw their booth at Summer NAMM a few years ago. Anyway these things last forever. I managed to break one once by stepping on it, on a smooth concrete loading dock, but that was after many other occasions of being smashed or stepped on. It actually still works it's just missing a couple teeth.
