It looks kinda cheap, like something a teenager or a first-time posting Chinese company would post on Geekhack ... ;-þ
And "Perfected" as a total regression from their ergonomic keyboards of the past... Bad for the brand, both the idea, the execution and the name. That's pretty obvious.
It being a staggered keyboard, I find lots of things to criticise — not necessarily flaws for everybody, but if you are going to design something for mass-market appeal:
More
* The Windows key is often used as a modifier, so it belongs on the bottom row.
* So does the Fn key, or at least close.
* They mention Mac support... but then they would definitely need another modifier on the bottom row. Or would they disable Alt or Ctrl?
* If the Ctrl key belongs on the bottom row, it belongs next to the left Arrow.
* Inverse-T would have been a better layout for the cursor keys. Because the middle finger is longer, the neutral position for the middle finger tip is in-between Up and Down on inverse-T. An ergonomic improvement would have been to raise it a row.
* People have muscle-memory for the function key row. Spacing is significant for finding them visually. The Escape key can still be enlarged to make it easier to hit (Fitt's law) but it does not need to be 2u.
* That is not DCS profile. It looks like OEM. ("Nano coating"... made by Tai-Hao?)
Things I think they did right:
* The modifier keys on the bottom row are convex.
* 2×1 Delete key.
* Modifier layer: Cursor keys on IJKL, Delete on D, Escape on E, Tab on T.
* Choice of space bar to reconfigure. Not just the left one.
* That they have macros.
I think I have seen that switch before... Gateron or something else?
