I have this keyboard through MechanicalKeyboards.com. It's my daily driver right now. When I first got it, I was definitely put off a little by the scratchiness of the keyboard. The people who are saying you need to hit it dead center are right.
I loved the layout and how well built the case was so I tried lubing the switches with some Krytox lube. I didn't do it "the most correct" way of taking the switch apart. I just painted some lube on each side of the switch that rubbed against the housing. It definitely takes some time but it makes a world of a difference. It's much, much, much more smooth now.
