They have hard to find computer parts
They have hard to find computer parts, and very often, are the cheapest out there. There’s a trade off for it. I’ve ordered a handful of things from them over the past decade, and every time there’s something - sticker or glue residue that needs to be removed, something sticky under a “new” keyboard key. None of it has ever been a deal breaker, and you do get what you pay for.
