Summary: i got mine at guitar center after thinking- wow played like a dream with great response in the keys. I got it home and babied it, but after a couple weeks I noticed it would wink out every hour or so. I'd have unplug it, restart my software and plug it in again. I figured it was my older pc or USB cable or something. a few months later I'd replaced my pc with a new MacBook and got a high end USB cable. didn't fix it. axioms tech support was unresponsive.
