Very good product (but pblm std Mac)

Qwerty keyboard (Fr) / ISO extended (keyboard arrows + + num pad. 14 + Fn + sound), compact and lightweight. Appealing to the touch, although a little hard when pressed.
Handy mouse and precise * * (movement speed with my old mouse: 10/10 (max), now 6/10!). Click a bit hard (but you can hardly click "unintentionally"). Ok wheel (mechanical?).
Easy connection through the small USB key provided (2.4 GHz encrypted AES 128b.), Auto connection. (The CD for Win anyway). Starting the keyboard + mouse connections * fast * (not had time to measure :-)).
Battery AA for mouse, AAA (???) for the keyboard.
* * NO LIGHT for "Caps Lock" and "Num Lock"! (Qq in fact. Have an idea to fix it (on-screen display with a widget or other)?)

In short, TB price / quality / usability.
To see: scope, autonomy (resistance to wear) ...

For the (lucky) owners of Mac OS X * *: The keyboard does not respect the std. Mac to qq. keys:
Easy: no "=" in the num pad. ; "Win" -> "Pom / Cmd" 8 :); "Alt gr" = "Alt" -> "Fct / Alt" ...
Dur: "+ =" -> "-_"; "* Alt / M" -> "£ '" ...
Very hard: "+ =" -> "§ 6" / ... "8!"
