Plus it has a rainbow backlight that makes it gay! 
I had been using a membrane keyboard that was so worn out sometimes I had to press a key twice. Now the keys glide effortlessly. 
It's just like playing the piano; speed comes from reducing tension in the fingers to allow the tiniest muscle impulse possible to accomplish the required motion, and having sticky keys makes things much more difficult because it raises the the key's "activation energy" (chemists' terminology).
My only disappointment is that I was hoping for even snappier keys. I once used a mechanical keyboard that was as loud as a typewriter. Apparently there are a whole variety of switches out there---again like a piano in that you can tune the "action" to your preference. It says I have "Outemu Brown" switches for whatever that's worth. Any switch stans out there? What are my options?
Red or Black if your a G*mer. Blue if you want the loudest clickity clacks and annoy all your neighbors.
But browns are Goldilocks baby bear keys. Clicky without resistance. Audible but not loud. Chunk chunk chunk.
I bought my keyboard with browns almost solely because that was the version on sale, but didn't realise how much I love them until I tried a friend's reds. That little tactile bump really makes a huge difference.
They're so much harder to get a hold of last I checked.
