Today we are looking at the Logitech MX 1100 Cordless Mouse. This mouse has some features you don't commonly see outside of gaming mice.
The MX 1100 is the first non-gaming mouse I have seen with a switch for adjusting sensitivity. The adjustment is towards the front of the mouse, right next to the left main mouse button. The scroll wheel can be pressed for middle mouse button click. This was something several previous Logitech mice using the free-wheel scroll wheel lacked.
