I'm using this stand to support my Kurzweil K2000 (61-key workstation keyboard), and I find the stand to be a bit too deep, so that the keyboard rests only on one set of pads, either the front or the back.
Furthermore, the stand is not as stable as I would've liked, but I guess you get what you pay for. Would get a sturdier stand if I would have seen it live, but I guess that's the nature of buying through the Internet! :-)
