The major problems with adverticles (adverts presenting as articles) like this is that they are highly opinion based as far as the actual products go, and often don't present the best value or products to buy. While the author may love them, how many people would look at the Akko 3098B, for example, which uses their own switch type, has 10 reviews, and would say "Sure, I'll pass on Razer (which use their own decent switches) or any of the many inexpensive mechanical keyboards which use Cherry MX switches and I'll buy this one for $98!"? Likely about zero.
Oh, and the "HyperX Wrist Rest: now $15 at Amazon (was $95)", it has a list price of $19.99, not $95.
