For the price, I really cant complain. I bought this to supplement my 400 watt hps. After adding this, the brightness when opening my tent actually hurts my eyes a bit. It definitely increased the speed of growth and my plants look absolutely perfect. I like that there are individual switches if I just want to run the veg switch and not pull the full 200w draw. I added this to my 4x4x8 and I don't regret a single penny I spent on it. Packaging was perfect. built super sturdy. Highly recommend. Id pick up one or two more if I were going to just do an led grow.
