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)
