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?
I never liked linear switches, I always wanted them since it's better for gaming but I couldn't get over the mistakes I was making with typing. Then I got a wooting which has Lekker switches and those still feel good for typing, not as good as tactile but still good while also having the benefits of linear (and full analog control on every key). I won't use anything else ever again, they are damn good keyboards.
