Good solo, less so in a group
This mouse performs its functions perfectly, and the scrolling of the wheel is very fluid, which is nice.
It took me a long time to work out that the USB adaptor was hidden inside the battery compartment of the mouse (perhaps because I'm not used to using wireless peripherals...). There's nothing about the user guide in the packaging - Logitech had got me used to better things...
And a bad point when using it in a room with several computers using wireless mice: it creates interference between them, and the cursor starts to do anything. Perhaps it's possible to make a setting to overcome the problem, but in that case I'm back to the user guide, which doesn't give any information.
