Most are:
* Ergonomics well thought with the palm rest pleasant, and well in his place,
* Silent and clear keys typing,
* Feet elevations well proportioned and ideally placed for optimum stability ....
*'s Quite dynamic blue slice ...
Cons:
* I see only one now. The space bar seems "fake". It is the only one that is almost unstable, too "lightweight plastic" and making lots of noise. A missed on "my" keyboard or the series? To see!
I therefore recommend this product knowing that I'll watch this space bar which "seems" so fragile.
Finally, Logitech could "let go" color side and propose real color ranges.
Blue is so pretty that we would like a little more fancy and joy for this material!
A five star so who would rather be a four and a half, but definitely not a four.
I recommend Logitech products that I find well made, cared until today and always gave me 100% satisfaction.
