The fineness of the keyboard allows me to consider prevail in conjunction with my back to my laptop bag Toshiba Portégé R700 and mice, although this keyboard (750g) weighs half of the notebook (1.4kg).
I use it in conjunction with a Logitech M600, which allows the use of a single USB key "Unifying" for both devices.
Note: jOperation the mouse is tiny. Some months later, I realized that the key supplied with the keyboard is not working!
The packaging is almost entirely recyclable, except the plastic bag.
The surface is matte keys, but the keyboard surface is glossy, which is quite aggressive to the eye, especially sil there is a direct lighting in the ceiling, so I left the original protective film.
Note: the connection on a Windows 7 computer causes automatic installation of all Logitech software in less than a minute, with an Internet connection bandwidth. I can even wake my laptop a keystroke or movement or a mouse click.
The installation of the software before connecting the USB Blutooth is less straightforward and may require several on / off key to trigger its operation.
The lack of status indicators requires installation of SetPoint (26MB!) To indicate the status change of some keys (upper case, Lock. Num.) By a compelling visual display and a suitable tone. This is done automatically when installing the drivers.
I tried alternative software (TrayStatus and NumCapsScroll Indicator) but one was too small and the other planted on my Windows 7 Ultimate station (Ultimate).
In short, a generally satisfactory product and without surprises. I keep it.
