Summary: I am very pleased with the style and comfort of the PRUS2 presentation remote. It has excellent range and works extremely well for powerpoint presentations, allowing the presenter to move freely around the room and still control the program.
Pros: Very easy to set up with any computer, laptop or desktop. Comfortable to hold with all controls very accessible.
Summary: So many controls on this device! A dial on the right side for slide changing, page scrolling, or volume control! A laser pointer! Mouse control with buttons that's not hard to use! Range appears to be good, and no difficulties with USB recognition by a USB PC. Using the "Media mode", it controls iTunes and Windows Media Player.
Pros: Works with iTunes for music switching, lots of buttons, good range (~25 feet/8 meters), not infrared, no software needed
Cons: Button presses for certain functions confusing and unnescessary (laser pointer and "media mode")
