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: The PR-US2 was an excellent presentation remote until it stopped working after a few years of very light use. The issue may be with the USB unit, as the remote appears to function fine with a new battery. I see other users have had the same issue. If you don't want to take a chance on buying a very expensive laser pointer, buy something else.
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: This is a nice, reliable device. Battery lasted about a year with limited use. My only issue with it is that everyone in my group uses the same device, and we have yet to figure out if there's a way to change transmission frequencies. When we are in ajoining training rooms one of us has to stop using the remote otherwise we end up changing each other's slides. That's the down-side of having a longer range. But in general, we are very happy with it.
Summary: This is my third Keyspan wireless remote. I wore out the first one and I replaced it with the newer model, then bought another of this model. I train professionally and wouldn't train without my Keyspan. (The same goes for my colleagues.) It works wonderfully well and the battery lasts a long time. It allows me to roam around the room (my training style) and run my presentation anywhere.
Summary: This presentation remote is the bane of my existence. It presents a dizzying array of buttons, none of which you can click with confidence, knowing that you will advance to the next slide. Perhaps the designers of this remote thought of this as a feature: where will you go next? I've been embarrassed in front of large crowds, because the remote took me to the end of my slides, or wouldn't advance at all.
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.
