Go ahead, buy that cheap junk, then you WILL be an expert on shit, because thats what you'll be buying. Or, make them prove they are usingf Samsung chips, because they are not. they are Epistar, you know, the same company that makes chips for all the burple gargae Chinese lights. I'll garantee you these Alibaba boards and heatsinks are NOT the same quality.
We already had some asshole come here ttalking about boards he was trying to sell. He got a rude awakening when he found out what a pile of shit they sold him!
Antoher thing, try to get warranty service on Alibaba crap. Good Luck!
So Are HLG's baords worth the extra money? Damn right they are! Look through this thread at the comments on customer service, NO ONE will treat you better than these guys. My personal experience with needing support was that they went way beyond what you'd normally expect!
So you can save some money and take your chances, or you can do the smart thing and buy a product that has PROVEN to be top shelf.
And I'll be here laughing my ass off when those that buy counterfeit QB boards watch their lights die.........
