Summary: Quick, simple, and easy to use. I've been teaching with this model for the past 10 years with my lectures. I've tried other presentation devices but they are not has user friendly, nor do they have the additional features to access the majority of Microsoft programs as the Keyspan model does. Though a bit more expensive than others, this is the best I have found and well worth the investment.
Summary: I have a computer in the bedroom for a tv so a mouse isn't ideal for use in bed and watching Netflix. This thing has been great and for the price it is a no brainer! The distance works anywhere in the room, and the battery has lasted years now too. Nice little wheel on the side from scrolling.
Summary: Bought this item for the remote mouse control; I have an HDTV connected to my desktop computer over 50ft way using an HDMI cable form [...]. With the Keyspan PR-US2, I have full use & control of my desktop mouse including left & right mouse key and scrolling from the toggle switch on the side. Now I can browse the web, watch Hula & Net Flicks on the Big Screen in my entertainment room 50ft away from the computer, Very Cool. It Works Great and works through walls.
Summary: Trouble free installation and use. The only thing not super good is the little mouse pad -- it's not as easy to move the cursor as quickly and accurately as a real mouse. But given the small space they have to work with it's acceptable.
