I bought this keyboard from somewhere else, but seeing it is being sold on digitec maybe I can leave a review.
I love it! The feel when typing is a bit different from other keyboards, keys are "flatter" and have a shorter run, however this is by design and I find it very comfortable. It is also quite silent. It has a handy key on the numerical pad for launching the calculator.
Battery life is eternal! I bought one almost two years ago: batteries are still showing maximum charge on the keyboard display (and last time I checked the mouse battery level in Logitech utilities, some months ago, that was almost the maximum too). I admit that I didn't use it every day, but I do use it, and I am impressed by the battery life so far.
The mouse is ok. I don't love it as much as the keyboard, but I think it's good. The two modes for wheel scrolling are great! Press a button and the wheel switches to "fluid" mode, where it can spin freely, and you can scroll up or down super-fast!
The only thing I miss is the "right click" keyboard button. The function is invoked by pressing Fn+PrintScreen. Many other keyboards have a dedicated key, and I miss this a bit. The function keys are also a bit small, but honestly it doesn't bother me too much.
Overall I am very happy!…plus
