Maximus, I have a similar unit from the same company. I can tell you from experience the unit works's great. During veg my plants grow about 1.5 - 2" a day. Thats no lie. It's also easy to take care of. But if you are even somewhat handy you could easily build one. There is tons of info on how to build one right on this site. Just use the search.
