I bought one to help me learn the key commands for Logic. Didn't spend more than 10 minutes with it before find two keys that didn't do what they said they would. Yes, perhaps I could go through Logic's key commands and try to fix it, but isn't that what I paid them$120 for? It's going back to Apple (not an Apple product, although it is based on their keyboard, I just bought it through the Apple Store). If you're considering buying one, stop now and don't do it.
