After a month of use, I am generally satisfied.
The keypad consists of rounded and low noise keys, which is nice in a quiet environment. Some common shortcut keys are provided to prevent us tedious manipulations. The entire object, light although good size, is conveniently equipped with a wrist rest which the joints and helps in relaxation of muscles of the shoulders when shrapnel for hours.
The mouse, meanwhile, although less complex than the MX1000 I used a friend's, as it provides greater ease to use my laptop. Well proportioned to my hands, I appreciate the extras that facilitate the work (especially button placed in the thumb, and the internal cavity which can store the tiny usb antenna).
Some black spots but a bit dull this table:
The plastic keyboard, brilliant, tend to keep grease and fingerprints. It's pretty unappetizing.
I also wonder what is the use of small LCD screen to indicate the activation status of special keys (upper case, keypad, etc.). The activation lights on conventional keyboards were simple and effective. So, yes, it's pretty, but is it that this has an impact on the high price?
Finally, it is unfortunate that the keyboard and mouse are battery operated. I would have preferred to have an electrical charging system, like other Logitech devices. That said, I moderate my judgment: the life indicator Mouse battery telling me at first use 1093 days of autonomy ... two batteries every 1093 days, this is not ruinous.
Of course, everything is not perfect, but I think it is a very good product that fulfills its role properly extension.
