I bought the remote, not actually needing it for a week or two, with next day delivery. I've seen the remotes in action, and have used one in the past and I was terribly eager to get my hands on one... The first thing I did (after tearing through the packaging like a kid on Christmas morning) was plug it in and open up an old presentation. My lord! I sat there for hours going back and forth, using the blackout function (the screen fades to black at the touch of a button, incredibly helpful if you need to move on to something else for a while, or there is a break). The design is perfect, the way the usb receiver fits into the remote and turns off the power, and so elegantly retracts back out aswell.
I bought this especially for an AGM which I am chairing, and I refuse to return to the lecturn for every click when I am on a massive stage. For those who want to give really good presentations, and want to move around more and interact more with the audience, this is great. You are never tied down to returning or standing by the laptop/computer just to carry on. The lazer is also brilliant for pointing out things in pictures or videos (yet another way to keep the audience amused).
I always buy products from Amazon according to what others say in their reviews, and to anyone reading this and thinking about buying it. Then all I can say is don't hesitate one more moment.
