Probably increases ACCURATE typing speed by 20% and if that's all it did, it would be a five star product

I love coming into my office at night and typing on it in the dark

IMy last gaming keyboard had 'brown' style keys which I really liked the feel of but these Razer green switches feel even better and the sound is very satisfying when typing and barely there when gaming with headphones.

First off the Razer Blackwidow Elite that I got has the Razer green switches which are clicky and tactile, these switches give one of the best typing experiences ever
