Bought these a couple of years ago for $350 just to practice on. I have 22 acoustic drum sets and just couldn't get into the electronic drums; no feel, etc....They were working but one of the pads needs a new head. I had to move them and don't know how to set them up or wire them so anyone interested in trying them out needs to know something about e-kits. I don't; as I said I am an acoustic player so asking me technical questions will go nowhere.
