For that price its hard to argue.
I would say if your looking for a cheap light to get a few grows under your belt before investing in quality then go for it.
If your buying a light to last and be your main light for a couple years then keep looking.
My opinion is based not on experience but just on the company itself, I feel they make very very bold claims practically guaranteeing you 1.5gpw and I feel they are exagerating a lot of the specs, I know some of the older models had issues with burning diodes out but theres people on here who own them and no doubt swear by them, then theres the fact that they name everything 1000 and 2000 and such tryna mislead people to associate that number with watts like you replacing a 1000w hps or something. I dont know they just seem a little too cheap and sketchy.
