Summary: Nice
Comment: Does everything as advertised. The only thing missing (IMHO) is an auto-shutoff when the timer is not running (to save the battery).

Summary: Wireless Presenter - 2.4 Logitech
Comment: LOGITECH, INC. / LOG9313070403 / Cordless Presenter, 2.4 GHz, Integrated Laser Pointer, Black/Silver / Sold as 1 EA
The presenter is very comfortable in the hand. It uses 2 "AAA" batteries - easy to find when it time to replace. Having both a laser and a timer on the unit is very useful - 3 tools in 1. This was a great purchase.

Summary: I like it
Comment: It is really good, the first presentation remote control I have, and I guess I will use it for a long time.

Summary: Perfect
Comment: This presenter is perfect and great for every day use. As mentioned earlier this will work only with presentations!!

Summary: Works great
Comment: I love this product. Some people claim that it does not work with a Mac, but it works fine. It does lock up the Mac keyboard, so you cannot use the presenter and keyboard simultaneously. This is usually not a problem during a presentation and unplugging the USB plug instantly restores keyboard functionality. When you plug in the USB plug the keyboard setup dialog appears. You simply cancel out of this and everything works fine. Other highlights: laser pointer is strong enough to see in a brightly lit room, batteries last seemingly forever, controls are super-simple to use. Downsides: timer can only be set in 5-minute increments. I highly recommend this product.
