I've been pretty happy so far.
Since I've been involved since Beta, I've had to deal with a lot of software glitches and stuff while the bugs were worked out. The cool thing is they are constantly making software improvements and it's real easy to update. There's still a couple things I think need some work, but nothing that effects the livestock. The lights already have some nice features and the guys are constantly working to come up with new and improved stuff. Plus their customer service is second to none, which is nice to have when you are spending that kind of dough. So if you want to go LED, I would have a hard time not recommending them. No heat, quiet, color is totally customizable along with different programs. Ya, no going back for me, even though I think the perfectly setup MH/T5 combo still has a slight edge when it comes to overall visual color/shimmer.
