Summary: Flawless... for just three months
Review: Teaching with a presentation remote is a declaration of freedom. No longer having to seat in front of the computer to flip through my Keynote or PowerPoint presentations allows for more participative discussion. The Keyspan's cluttered yet complete interface provides all the functions of the competition at a fraction of the price. Moving the cursor, flipping pages, laser-pointing... It's all there. Regrettably, it only worked for just three months. I even changed the battery (a very expensive and even more difficult to find 3v model) but nothing happened. It turns out the original battery was still fully charged.In conclusion: I can't recomment this product. I have now ordered the RemotePoint Navigator. Hopefully I'll be luckier next time.

Summary: Worked Great & Then Stopped
Review: The presentation remote worked well. It provided good control of forward and backword motion for Powerpoint presentations. The RF technology did eliminate the need for line of sight operation. I really enjoyed using the product. Then one day, at the start of a presentation, it quit working. I assumed the battery had died, no one happened to have the special battery on hand, so I put it away. Later, I tracked down another battery for the device, put it in, and nothing happened. I checked voltage levels and the battery was fresh. So, I contacted Keyspan for warranty help. And after 3 weeks have not recieved any response. Hopefully, someday, they'll respond and fix the device. Without the service problems, I'd give the device a 4. With them, it seems your choice is to purchase and hope it doesn't break.

Summary: Not recommended - jog dial used is awkward
Review: This is my second rf remote. I purchased Keyspan model because of smaller receiver size (as compared to the remote from Mind Path). That was a big mistake - buttons positioned uncomfortably. Main button for advancing slides is on the side like Sony's jog dial. During my talk I could never advance slides forward. Not recommended.

Summary: Tendency to fall apart
Review: This product works pretty well. And have used it fairly often. One thing I noticed, though: I had just been using it for a week, and the battery cover of the remote would no longer lock on. I have had to use masking tape to keep the battery cover on, lest the whole remote will not work. Oh, yes. One other thing: the remote's battery (CR2450) isn't exactly that easy to find available in stores, either. But the remote works!

Summary: Sleek and Affordable
Review: This remote is excellent for those who spend a lot of time teaching or making presentations, and abhorr the thought of being perched behind a podium. The coverage is excellent, and the size is small enough to almost disappear from view. I actually position mine horizontally, using a rubber band to attach the bottom of the remote against my belt with the top latch hooked to a belt loop. The only issue I would have, if I were big on laser pointers, is the activiation of the pointer itself. Other than that, this is the best I've used thus far.
