Review on RF 2.4GHz USB Rechargeable Green Light Presentation Remote - Wireless Presenter Clicker For Mac/Keynote/PC/PPT by Richard Eledge

I was looking for a way to have someone else change the powerpoint slideshow for church services and this works great. We have a computer attached to a projector at the front and no easy way for someone else to change the screen slides. I tested the distance by walking outside to the end of my driveway to see if i could change the screen on my computer inside the house and it worked. I have yet to test the range in my church but i know this will give me the freedom to have someone else control the screen during the service while they are sitting in a pew.
