Run..., do not buy from them, poor customer service.
Agreed with other posters here. Their customer service is abysmal. Because the company is out of china, and they franchise with local warehouse sellers to sell their product and represent. Mine came from NJ, and the customer service is what you expect from NJ. No confirmation email..., no tracking email, and the item arrived 2 weeks later. I paid with paypal, and the address of the seller was an "hotmail address" which always rings some bells, and the main name of that paypal account was "New Pearly Luster" which is a chinese toothpaste. So yeah, this is a clearing house in the U.S. (NJ) that sells different products from china. They are only a mars hydro distributor, and sell other products first and foremost. If you don't like doing business with companies that are iffy...., buy another type grow light. I still have not tested it to see if it actually works, because I just got it today, 2 weeks later from NJ to NY. Avoid this company.
