I bought two of these for a midi controler that I use for looping audio samples, and have set these to record and play the samples. They certainly have a hefty construction, and feel like you could back over them with a truck and nothing would happen to them. They are only switches, so there's not much to them, but the one piece of information that I feel I must pass on is that they don't have much travel, so they would not be a great option as pedals for a keyboard (they would work, but not well).
