Amazing choice

The keyboard was delivered, as promised, in 6 working days, nicely packaged. Upon opening the package I was greeted with an amazing keyboard and all the tools and extra keycaps. The quick-start was handy to have.

The actual keyboard feels truly great. The build quality is very high and the typing experience is very nice. The brown switched are very silent and i have had 0 complaints from colleagues. The ability to assign different functions to all keys really suits my workflow since I love to macro and make shortcuts for everything. The ability to switch between cable/2.4GHz/BT is very handy and works flawlessly.

Truly an amazing purchase, definitely considering the price.
