Positive side, the fact that the mouse accepts two AA batteries (rather than AAA) must offer good battery life, weakness of Bluetooth mouse. The mouse itself is previse and seems to work on all surfaces.
The confusing point and the Touch Pad in the middle: for accelerated scrolling is nickel, but for the precision, it is much less: Amateurs PowerPoint and Visio, go your way ...
I'm not thrilled with the side scrolling, but I used it when not offered the wheel functionality over previous mouse.
