Positives:
Ergonomic shape, really run extremely significantly (Ie: Extremely good and "dramatically", not a tiny curtsy and then ergonomics draufgeschrieben). Feels good.
Neutral:
Some additional keys, safe practical for many, I (at least not at work) need rather not.
Runs directly after plugging (driver I can not install on the work). (Not Zoom) Basic additional keys also work.
Negatives:
Processing: The space bar is loud and slightly stiff, the biggest shortcoming. By that I do not trust to tap me in the office. The one or the other key when you press feels "sticky" on, which means you pressed it down (which already needs more power) and then she comes slowly up again, as if the a little stuck. Most I've noticed from the Numblock on the +. In the letter, everything was fine.
It's a nice keyboard, the ergonomics and fit but the spacebar is atrocious. Even if you can stand the noise then it still feels a little sluggish at what extremely disturbing. Here I would nachwerfen a few euros more if they make Microsoft happy processing neater.
Very sad, tomorrow I will send them right back: - /
