I'm using a Windows 10 PC and PowerPoint. I just plugged in the USB receiver, opened PowerPoint and disconnected. No setup is required at all. The button above toggles the black screen. The bottom toggles the presentation mode. I tested it about 25 feet from a receiver (the size of my room) and it worked great. I think the wider bottom and thinner top version (6400A) will be more comfortable in the hand, but that's a bit of a quibble. The K100B does what I need and is cheap therefore 5 stars!
