Product Description:
The Keyspan PRUS2 - Don't start a presentation without it! This RF ( Radio Frequency ) remote works from up to 40 feet away.

Rating : - Great so Far.
After a couple weeks, so far so good. Syncs well with multiple laptops, has good range, and is responsive. I use it for executive presentations, and my wife uses it to teach classes to groups of ~30 students. Gives you flexibility to be more interactive, roam away from the laptop, and you do not have to walk into the audiences view to advance a presentation or other demo.
