I've used their T5's for 6 months and it was great. It just stopped working one day and I didn't bother looking into it, but that $65 temp lighting gave me 6 months to save up for a better light. The one I got didn't put out quite enough light, but when I raised my Zoa's higher, they loved it.
Their MH's get hot and tend to melt, but it's a MH ballast, they do in fact get hot no matter what brand it is. They just place the ballast inside a cheaper cover and it'll melt, that's common sense if ya ask me. You're getting what you really pay for IMO because you can call and have a custom one built the way you want it. It'll obviously cost more though.
