I voted three. The first had a busted C with the plastic lodged underneath making it useless. I returned it and received a second unit with the same problem plus two additional lifted, but working keys. I returned this, too, and decided to buy from an actual store. All the keys work on this unit, but three are lifted and look ugly. I don't have the time or patience to keep sending these back. Like Stefk, I wish I had read this before buying one. Hopefully I can record the rad audio before all the other keys eventually crap out on me.
