So here's my first review....
Initial thoughts:
Wow this keyboard is heavy. Feels like tank. I was grinning the entire time as I removed the plastic cover and dug around the box for the USB cord. The keycaps feel great and feel more durable than on my K90.
Typing:
Being that this is my first cherry mx brown keyboard it was odd and a mixed bag of emotions. At first it felt nice and I liked to type on it. After a day it got to the point where I was wishing I bought it with cherry mx reds instead. But now it's an absolute joy to type on. There is only one key that pings (A) and is on audible if I put my ear to the keyboard.
Package contents:
A wire keycap puller, alternate space bar, USB cable, and wasd red replacements keys.
Dip switch:
The dip switches change various things on the keyboard
Windows Key disable
Ctrl and Capslock swap
Windows key and Alt swap
DEMO Mode
Build quality:
The keyboard feels absolutely amazing. I could kill a man and still type. There isn't much flex if any.
