Here in Argentina, HyperX is very popular due the agressive price and also offer VERY good rewards to the resellers. The quality is very good on par with the big names. I don't see in my job too much RMA of their products specially the keyboards, they rarely fail.
I own a Alloy FPS Blue over a year ago and is working just fine, the only complain is the space bar is a bit loose. I tried the Alloy Elite the construction and quality is very similar but with rgb and media keys, i doub about the durability of that "volume wheel" and the arm rest is a cheap ass piece of plastic.
