Really top! 3 2

Logitech proves once again its quality!
Many of my colleagues use it and now it's my turn.
This Mx to a really good grip for a mouse designed to be mobile!
It works on all surfaces thanks to its laser sensor.
To my surprise when opening the box I discovered a storage bag to be able to carry! It's great and more housing for storing the sensor and cover office doing button On / Off! Really handy for the safe transport with his laptop.
As regards the side buttons no problem, on the other hand the adaptation of the wheel is not obvious! It is difficult to get used to press the button instead of the wheel to open a new tab in the Internet. For cons, the idea of ​​the toothed wheel or not is really great! I wonder if the passage of the toothed wheel or not would not have been better in place of the button instead of click the dial as the M705. It's mostly a matter of habit but it does not help when returning on another mouse :-)
Small remark about her weight, she is a bit heavy but having 2 AA battery does not help I think.
The price is worth it (Plus Amazon has offered superb flash sales!)
I really recommend!
