Small optical mouse or presentation tool? SlimBlade is both

This Kensington SlimBlade optical mouse looks like a great addition for any speakers, presenters or folks who like to annoy cats with laser pointers. For under $70, the wireless mouse includes a 2.4 GHz USB receiver for your mobile device and offers two buttons plus a small scroll ball for 360-degree navigation. Turn it over and flip the Mode switch to enable presentation mode which offers a laser point out of the front. You’ll also see media playback buttons on the bottom-side; great for controlling volume, flipping through slides before the audience falls asleep or for navigating audio tracks. The two AAA batteries should last about a half-year, which your cats are sure to appreciate.
