Ticking the $67 off coupon box
…brings down the price from $135 to $68 for gateron black switches. I don't have experience with this keyboard brand nor with the gateron black switches but seems like a decent price off using the coupon and has decent reviews. Some caveats being wired only connection and keycap style may not be that appealing but hey… it's got RGB ¬‿¬

I have this keyboard (or at least a variation of it in the Yunzii KC84), it's a nice entry into customising keyboards, there are some downsides though which limit how much you can mod it.
All in all, it's a decent entry board for the price. IF you are looking to spend a bit more, then there's far better boards out there like the Zuoya GMK67 or Feker IK75 etc which have far better features (gasket mount, wireless, pc plate etc, better sounding and better mod-ability)
