Rating: - Better than I expected
This wire-free USB unit is portable, smart looking, and very effective. Being wire-free in some set ups and offices is very valuable.
There aren't any other units nearby, so I can't be certain that if there is more than one, there won't be "cross-talk." I would find it surprising if this was a problem.
Rating: - Presenter Mode Only
I'm looking for a presentation mouse that will allow me to move the mouse around the screen, like a gyro mouse. This mouse doesn't do that. It does allow you to switch to presentation mode and click through pages of a powerpoint presentation for instance. I had to look in the product manual on the Kensington website to find that out. Otherwise it appears to have great features.
