The keys are exactly as described here in other reviews: quiet but not dead quiet, with a pleasant feedback. Only the space bar is actually "sonorous", but the good impression you do not mind. Very nice also that the keys are installed individually and not because of the construction debris collectors (like my old keyboard). The keystroke is so pleasant that I can write noticeably faster (and I write a lot), and I also generally hands hurt less after that, which indicates a good ergonomics. What's also like that the Tatstatur thanks to the rubber feet at the front and the quite noticeable own weight very slip-resistant sits, my old keyboard (by Logitech) was there but significantly more flexible, which was not necessarily very pleasant.
Visually it also makes a good impression, so they certainly improves well-being at work is also not unimportant. The connection was plug and play without rebooting, only the SetPoint software had to be downloaded separately, and with the exception of the function keys are not many settings anyway possible as the Logitech K280 yes is a very classic keyboard without unnecessary (for me) buttons. I am not a gamer and more like 2-3 buttons simultaneously I also do not use, so I could not tell you what it looks like in this area, but de K280e is not even made. Made it is for office purpose, for those who type a lot and that's what it provides and even very good.
I would like to thank everyone who has been rated the Logitech because the reviews helped me a lot in the selection and they have led to a good selection. It's very true is not always so in reviews, but in this case.
A very good Office keyboard, the good, even in terms of ergonomics, leaves an impression. For this very valuable built. So a very good choice for all that much typing. Class keyboard, even if there is this just only in black, but is also beautiful.
