LFS here has sold several of them, and had them on demo at the store for a few weeks. pretty cool lights! I got to mess around with them a few times. the lightning mode is a cool gimmick, but i'd never do that to my fish. maybe once a year when showing off for a crowd of people. maybe. but other than that, that mode seems silly.
as for the rest of it... they are VERY well built, and are pretty bright. the color customization is really really nice, and no need for a controller, when you just run a USB to your computer and set it all up.
the only thing i dont like about them, is the 3 "touch" buttons on the actual unit. unless its hooked up to a computer, they are VERY difficult to use and set up.
that being said, if they were $400 a unit, instead of $750, i'd probably own a set of 4 right now.
