Excellent quality, even down to the power cord. The only complaint I have is I wish the power cord was a bit longer.
Also just a suggestion, when you get to choose the switch for your keyboard, put the switches full name. Ex: glacier silver switch, instead of just silver switch. It was mainly my fault for not reading the product specs, but I thought the keyboard just game with a silver switch, and if I wanted the glacier silver switch I needed to buy those switches separate. I realized after I got the keyboard that it came with the glacier silver switch.
Not a big deal, like I said, it was mainly my fault for not reading the specs, but I think that would eliminate any confusion for future customers.
