Title: The usefulness of the Cordless Presenter
Review: Free to move around during a lecture is important to me. This little device, comfortable in my hand, allows me to just that. The laser pointer is strong enough to show up on the screen even clear across the hall, which is great. The vibration of the Presentor warning me to come to a close, is most helpful and worth its weight in gold. I have not had to change the battery after several weeks of intense use, another great value.
