I owned previously a Microsoft Wireless Mobile Mouse 4000 and I was really satisfied. Unfortunately, the latter has made the soul (well almost, the wheel began to falter seriously). After much research I set my heart on the M560 Logitech. I did not want to put a fortune, or opt for a virtually unknown brand. So naturally I ordered it. In absolute terms, it is properly what one asks him, especially since I use my very basic field mouse (point, click, scroll ... and that's it!). Still I find it less accurate than Microsoft, with a much less flexible click. So sometimes I have to take me there twice to open a link or even a file. I think I'll have to get used actually. The grip is good with a natural position of the hand on the mouse. The 2 buttons on the side are practical, unlike the central button that, to me, is purely gadget. So a good buy in conclusion, a very great price ... Recommended for those who want a simple mouse usage for off gaming.
