Perfect Presentation Remote
I read all the reviews of the various presentation remotes. I liked the timer function on the Logitech model but I ultimately decided on the Keyspan Presentation Remote because of some comments about how the wireless receiver plugged in and the built-in mouse capabilities. I don't expect to use the wireless mouse capabilities much but the feature didn't seem to get in the way of the standard forward/backward functions and could come in handy for some future use.

I was very pleasantly surprised by the size of the Kensington Remote. It's about 1.25" wide by 4.75" long and less than 1" tall. With the rounded corners it fits easily and comfortably in your hand. My thumb falls very naturally on the forward/back buttons and it is easy to operate without looking at it. The laser pointer button is just under the forward/back buttons.

The receiver clicks securely into the remote when not in use and there's no way to put it in upside down or backwards. Windows XP SP2 recognized the receiver immediately and installed the proper USB drivers automatically. I then turn on the remote, launched a presentation with the "F5" button and moved forward and backward through the slides with the arrow buttons. For those who prefer there is also a small, spring-loaded click-wheel on the side. At the end of the presentation I clicked the "black screen" button.

My only complaint is that I wish it came with a small nylon case to protect it in my laptop case. Overall I think the Keyspan Presentation Remote is the perfect presenter tool to free you from the computer keyboard and allow you to concentrate on your presentation and audience.

Works as expected--good news
I bought it for a conference presentation, as my old Targus remote was unreliable. This one is nice and small without being TOO small. It works as advertised. the joysick mouse is a little hard to use due to its size, but with practice should be fine. The laser is a little weak, and a green laser option would be wonderful. The one design difference I'd recommend is to put the fwd/back buttons at the top of the remote rather than the center, but I understand its current configuration is to put the mouse buttons in the expected place above the mouse. I like the blank screen toggle button, and would love to see a white/black blank screen option, probably would have to be a different button, but fine. A short form dongle would be great too--like some of the new bluetooth dongles. All in all, very happy with it and would buy it again, especially with the suggested changes.

Great Remote! Tip for Mac/Keynote Users
This remote has been outstanding. Great range...super simple to use...great size.

Here is a tip for Keynote users on the Mac. The remote is set up with non-programmable buttons, so the F5 button (designed for PowerPoint) doesn't work for starting your Keynote presentations...but it can. The trick is to change the keyboard shortcut in Keynote for Play Slideshow from cmd-option-P to F5. On Mac OS X v10.4+ you can go to System Preferences > Keyboard & Mouse and then the Keyboard Shortcuts tab. Click on the + icon to add a new shortcut. Choose Keynote as the application*, 'Play Slideshow' as the Menu Title, and then when you get to the Keyboard Shortcut box, hit the F5 button on the remote and it should insert F5 in the box (making sure, of course, that the USB receiver is plugged in to your Mac). Click on Add and you're all set. The next time you launch Keynote the new mapping will be in effect and you can now use the F5 button on the remote to start your slideshow. Hold down the F5 button for about 7 seconds to send ESCAPE, thus exiting the running slidehow.

Fantastic!

*Keynote may not show up in the pop-up list of applications because it is inside the iWork 06 or iWork 08 folder inside the Applications folder. To find it, just scroll to the bottom of the pop-up list and choose Other... You can then navigate to /Applications/iWork 08/Keynote to select it.

Our room seats 100. So, we needed equipment that would cover more more than the 50' or less of most remote presenters. Because of where the equipment is located, we needed RF rather than IR. This presenter has been outstanding. I would recommend it highly.

Everything you need for presentation
I present for a living and have used many different presentation remotes from the new gyro mouse to much more simple remotes. This is BY FAR the most reliable, has the best distance, and smartest design (the USB receiver storing inside the remote). Many like the rechargeable battery designs, but I prefer the replaceable battery. It allows you to always carry a spare battery with you. If you forget to charge a rechargeable remote or it somehow discharges, you're SOL. The fact that it has a mouse feature is also nice if you do presentations outside of PowerPoint. It really allows you to present using all your computer's programs, as long as you don't need to use the keyboard. The mouse is very sensitive at first, but with practice it is easily mastered. The black screen feature, presentation start/stop, and every feature you might want works as advertised. It's rare to find a product that does everything it says it will do, precisely and reliably. This is one that does. I highly recommend this remote for anyone doing presentation on a regular basis.
