All in all, very ambivalent

I have this keyboard actually only gained because I finally wanted to do something new.
My Logitech Cordless Desktop Deluxe has now already 12 years on the hump ... (but still works perfectly).

My requirements were quite clear:

Lighting, mechanical, resilient and what for eternity (at least 10 years, they should already participate)

I want the keyboard to work with both, as well as use for occasional play.

Logitech dropped out because I was the declining quality and the rising price of recent years simply deterred.
(Just as the deteriorating service)

The choice on the market is not so big as you think, so stay actually (for me) only the Ryos MK Glow left.

Positives:
+ Driver works properly (aufwachproblem I did not)
+ Stop perfectly, after settling a really gigantic typing feel, I type much faster than before
+ Weight class, will not budge on the table
+ Lighting super
+ Palm rest more comfortable than it looks
+ "Set" the springs of keys still be a little bit, then the attack is really perfect

Actually, there is not really something to complain about at a quick glance, but after a few weeks playing small details which have been verschmerzt a greater role than to the beginning.

Negative, after some time of use:
- The macro keys on the left are too close for my liking to the main keys, it is constantly in front of the M4, I press Shift instead (the work really annoying)
- The keys have the quick release a strong mechanical Hall, "tap" when not as flashy as in individual keystrokes
- The thumb buttons I'd like to nail the manufacturer on the door ... This is an absolute absurdity, the clack as Russian power relay (ergo I totgelegt it, eh unusable)
- If you make a second assignment already a FN button (like the laptop) then you should also 2 FN keys as his (left and right, or FN-Lock key), up / down, etc. are thus only ambidextrous reached and the "Multimedia function "is no longer valid

Conclusion:
I'm actually really happy with the decision to buy, I would be even happier but if they would have cost either 20 less (which makes the design error verschmerzbarer) or the manufacturers would have just left out these errors.
I ordered the Kone Pure to, so I put the multimedia features of the mouse and no longer need the keys on the keyboard. (If it were not, I would probably go forward to 3 stars down)

In short:
Both to gamble and to work ideal.
The relatively high price leaves a but often think about whether it is the "old man" would not have done just a few years (which was just perfect)
