As small as it gets if you still need a numpad

The K4 is surprisingly compact without any big compromises. The smaller right shift key and the arrow keys being closer to everything else take some getting used to, but that's a small price to pay for a MUCH smaller form factor. And since everything is the "normal" size and you still have a Numpad, it doesn't take long to get used to the new keyboard.
The keys feel and sound VERY nice and the switches (brown in my case) feel very good for typing and even gaming (in that order). I will definitely recommend this keyboard to anyone who wants to switch to a mechanical keyboard.

The Gateron blues greatly annoy my family.
Perfect

Battery level and selection switch button

The K4 is my first mechanical keyboard, and up to know I enjoy it very much. (Gateron Brown).
What annoys me a little is the lack of proper battery level of charge and the Cable /off/Bluetooth selection button that is a pain in the neck if you have to change selection.
