I really like the ergonomics of this device. It fits very well into your hand. It is easy to advance Power Point slides with either the right pointing arrow/button or with the mouse click button under the front part. The killer app and why this is worth considering is that you can pair more than one receiver to this clicker. I now have two VP6499 receivers advancing Power Point decks in perfect unison.Also--the range is great. At least 100' as tested. Also, the laser pointer is super strong.
