Summary: This product was designed for people doing presentations and not for someone who wants a handheld mouse (if you want that buy something else). It is small (2.6 x 6.7 x 8.4 inches ; 8.0 ounces). Works well with PowerPoint, showing pictures, and Adobe. Standard AAA batteries are used and are even included (don't see that too often anymore) and has an on/off button to conserve battery power (can last over a year). The convenient neoprene case protects the device and the USB receiver is housed in the presenter. The laser works from distances in excess of 100'. Great for small, medium and big rooms, just stay within 50' of the computer. This device is priced than its competitors and also has a 3 year warranty. Good product, good price, good buy.

Summary: This wonderful little product is well-designed and perfect for PowerPoint presentations. The USB dongle, when not in use, is stored inside the main unit. No software is required to get the unit running; WindowsXP recognizes the dongle as soon as you plug it in. Using 2 AAA batteries means you won't have to look hard for replacements.

Summary: This product simply does what it's supposed to and does it well, which is rare. The Logitech Cordless Presenter is a welcome companion to any projector and a definite replacement to the OEM remotes that accompany most projectors on the market.

The Cordless Presenter manages the basic navigation and presentation control commands for any PowerPoint presentation, such as 'blank screen', F5 (start presentation), advance and back. But that's not all. This device also includes a laser pointer, an LCD timer display which can be set to the length of the presentation and a vibration feedback warning that will alert at 5 adn 2 minutes from the programmed end of the presentation.

The Presenter has a 50 ft. operating range from the USB dongle and runs on 2 AAA batteries. The USB dongle snaps into the end of the Presenter so there is one less thing to misplace. The Presenter also comes with a protective sleeve which easily stows away nicely in any projector carry case.

This Cordless Presenter retails on the high side of the presentation remotes, but includes functionality that it's competitors lack. For my money, this device is a 'must have' for any mobile professional.
