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.
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.
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.
Summary: Have used my Keyspan for over three years - only changed the battery once; how? When you are done with your presentation, flip the battery over in its space - no pain and no drain! You'll only start a presentation once without flipping it back, presuming you are trainable!
Summary: I recently converted my six-hour workshop from old-school transparencies to PowerPoint (see my review of Beyond Bullet Points), and someone I deeply respect said to get the Keyspan unit. I did, and it's great!
