The Phaser 3-in-1Presenter / Mouse is an excellent tool for mobile professionals, gamers, and desktop users. With no wires, you've got the freedom to walk around the room during your presentation. Compatible with both PCs and Macs, the unit's advanced 27MHz Radio Wave technology allows it to work at any location and from any direction within its 30 foot range. Even nicer, there's no need to point the mouse toward the computer or sensors. The thumb-operated omni-directional cursor control allows the unit to work as a full-functioned mouse, as well as a remote presenter. The built-in laser pointer helps you to direct the audience's attention to where you want it.
