I posted this in the other 69 edition thread so I'll copy it here.

I actually bought two of them (#0162 and the second was I think #0090), and unlike a full MX green keyboard, putting MX blues on the modifier pinky fingers (except the alphanumberics that still have greens) and the space bar really works very well for gaming. For typing, this may not be ideal, but you don't want heavy switches on shift and space especially in FPS games when you will be mashing those keys often (although you might not want keys that are too light too, e.g. reds).

The color scheme is beautiful and in horizontal wave mode, the way the red/green (yellow) and blue/yellow (purple) LEDs are laid out, it could almost pass for a limited palette RGB.

To understand Ducky's color layout, notice how the red pattern moves left to right. When the pattern goes over keys that don't have a red LED (the blue/yellow led keys), it turns yellow instead (that being said, the blue/yellow dual LED isn't really yellow...it's more like a cross between tan, orange and yellow. Maybe a sharp Beige is closest to this color. You can tell the difference between the red+green combo at full (=dirty yellow) vs the yellow/blue LED at full yellow and blue off (full red+full "beige"). Seriously, try the color wave pattern (left-right), but make sure the two LED colors are set to full (fn+f5 and fn+f6). The way red transitions to "Beige" on the blue+beige (yes I know it's called yellow) LED and then with those turning to blue and purple, makes it look as pretty as a RGB board.

I do think that putting MX blacks on the arrow keys was a bit boneheaded. MX Clears would have been much better (since arrow keys are used often), then you maintain tactile consistency over all of the common keys. Even Tactile greys on the arrows would have worked. I suspect this COULD have been due to some gamers using arrow keys instead of WASD (ESDF) to move, then greys would be quite too stiff (but still, why not clears? Or MX milk whites?). Maybe "right handed" movers (people who hold the mouse in their left hand and use the arrow keys tn their right hand) might see a benefit to blacks on arrows and reds on numpad (In a way, such a bizarre setup with a left handed mouse could make sense for HOTAS users, who used flightstick in their right hand and throttle in their left), or some normal handed (right mouse hand) people who simply like arrows+control to jump, may use that. (rant over).

I'd rate the keyboard 9/10. 10/10 if there were MX clears, milk whites, or tactile greys on the arrow keys instead of blacks...
