I can certainly agree about DROK-branded products, they've been great for the price. Apparently the brand is well-known enough to warrant counterfeiters: I ordered 2 5V buck converters and didn't pay enough attention to the seller. The description said DROK but I received some generic boost converters, all of which were inoperable. It wasn't worth going through a return for such a cheap item, I treated it as a cheap lesson on being careful in Amazon.
It just shocked me that someone felt the brand was trusted enough to justify faking.
