Although the keyboard is heavy and has a great design, from what I can tell, it has many marriages. I once gathered stuff, put it in a box, and immediately ran to the post office to return the items after learning of two marriages! Respectfully, the items were delivered back to them in just two days, and the money was repaid on the same day I was given permission to return them. I'd like to conclude by saying that the keyboard would be perfect if it had regular switches, like red (with RGB lights). I therefore chose the GIGABYTE Aorus K7 RGB Gray USB as a substitute.
