Unfortunately the pressure point of the keys is not optimal. The keyboard latches very cheap. For almost 90, I expect a higher quality keyboard. My notebook from Samsung, which also has an illuminated keyboard, has a better tactile feedback than the Logitech.
The touchpad is a bit too small, make it better, the entire housing slightly larger, but also the touch field larger.
The illumination of the keys is sufficient.
The F-keys are only accessible via the function key "FN", it is the key with these multimedia keys, search button, and so on. Has its advantages and its drawbacks. I need more the classic F keys.
Who wants to work with the keyboard should be the acquisition of 2 times superior. As a multimedia keyboard this is probably appropriate, but no more than that.
No 100% buy recommendation from me.
