wheel mice

I was very pleasantly surprised by the RF range of this product. After you work out all of the settings, you can do what you need to do from a good distance away, unlike many of those lousy IR Keyboards and mice. No messy or clunky transmitter either. All you need is a USB port on your computer to use a small dongle-sized USB transmitter. If you are running an 802.11b/g wireless network, you have no worries either as these devices run on a totally different frequency band.
The keyboard is solid and easy to use, with some nice one-touch buttons that, sadly, don't seem to be customizable.
The wireless optical scrolling mouse, although functional, is a little small for my tastes. You may run into problems getting the mouse to work but, once you fix that issue (by using a pen or paper clip to synchronize the channels on the transmitter and the mouse) it is a nice item. To save battery power, the mouse will go to sleep/power-off when you're not using it, so I typically just roll the wheel or move it around to "wake it up".
The communicator remote is a really nice bonus as it is an almost seamlessly integrated product with Microsoft PowerPoint, and is a great little tool for doing a presentation. For the money, this is an excellent product to have, even with it's little imperfections.
