I know most products in the market from Chinese made, since the labor cost in China is really low, that's why some big companies in USA would set up their factory in China or some other Asian countries for example in India, Vietnam or Thailand, etc. Apple gets most of their parts made in China then ship to USA for assembling. I think not all products from China are bad, some of them are good.I would say Epistar from Taiwan is relatively good compare to most expensive ships in the market, the price /efficiency is acceptable for most growers i think. My pro ii 600watt epistar one from marshydro led, but it's not bad in my opinion, my plants love the light.
