I've been using mine for about a year now. I love it. I'm not really an orthodox touch-typist so there were a few keystrokes that took some time for me to get the hang of. I'm pulling 100 WPM though so I must be doing something sort of right :)

The customization of both the RGB and the keys themselves as well as the ergonomics have been well worth it. I use a USB switch and use the keyboard for both Windows gaming and development on Mac.

One quirk of my typing style is that I use my right index finger for the space bar, so my left space bar effectively went unused when typing. I rebound the left space bar to the Command Key on my Mac profile so I can use my thumb for it like I would on a Mac keyboard.

I use it for gaming too. Sometimes I move the right side completely out of the way so I'm just using the left and my mouse.

I'm not saying these are all features exclusive to this particular keyboard. But a split keyboard was a great investment that I'd recommend.
