The mouse is very well made. Logitech knows how to make quality things.
The mouse is wireless - the wires on the table will not interfere. Wireless is provided by the new tiny Unifying receiver - first, as already mentioned, it is very small, probably the smallest on the market. Secondly, if you use/plan to purchase other Logitech wireless devices that support Unifying, you don't need to plug in separate mouse and keyboard receivers. One is enough. As far as I know, the receiver processes up to 6 devices simultaneously.
In the hand, if the hand is not very large, it is very comfortable. Everything is in its place, additional buttons are easy to access. By right - one of the most comfortable mice in terms of grip. Batteries really last a very long time (according to the testimony of the Logitech SetPoint program) - in a week of use, the battery charge dipped by only 5 percent.
High-speed scrolling is something incredible! One has only to try, and all other mice without such an opportunity seem inferior, and normal scrolling is terribly slow. High-speed scrolling is enabled by a separate button, which I consider an advantage. If you need fast scrolling, turn it on (and it is very useful when working on the Internet and editing and viewing documents). Need step-by-step scrolling, for example, in games or applications where special accuracy is important - turn on the normal mode with clicks. But to be honest, I completely forgot about it (about the normal mode), because there is no time for games, and in all other programs I use fast scrolling. At first, it’s even just fun to run this wheel back and forth. :) It can spin for 8 seconds without stopping!
The hidden button under the thumb is very interesting. You can put any action you want on it. By default, it is responsible for a kind of Alt-Tab, only improved - all windows are reduced and arranged on the screen. Convenient and simple.
