A mouse-road business

Mouse bought for business purposes (not gamer).
Unpacking, these are the first comments:
- The mouse is quite big, not the type to slip into a small pocket computer,
- The receiver is almost invisible once in the USB port
- The accessories are many (USB cable, USB charger, USB extension cable to the receiver, all in a small package.

After a few weeks of use here are my comments:
- Unlike other Logitech, the receiver can not be stored inside the mouse
- Autonomy is 3 to 4 days under the following conditions: 6 to 7 hours of use without extinction after use.
- The buttons are programmable hyper and quite easily accessible
- And the top is that you can really use it anywhere without carpet -> she is not afraid transparent surfaces, hard or soft (tried on a quilt in bed, nickel)
