Excerpt: This handy little device has been incredibly easy to use and intuitive in its application. It is comfortably held for long periods of time (i.e. for long presentations). It has been used in many computers (Mac and PC alike) and each time the software in the computer easily recognizes the device and incorporates it into the Computer Presentation (such as PowerPoint or Prezi) making it completely unnecessary to tinker around with the computer to get it to work through...
Pros: Durable, Easily Viewed, Intuitive, Lightweight, Long Lasting
Excerpt: The Presenter R400 is comfortable in my hand. The remote presentation device I was using before had squared edges and I could not tell which way it was pointing just my feel. The Presenter R400 fits in my hand so that I can instantly which direction it is pointing. It has worked well in all presentations I have used it. The red laser light is bright in all distances. The button are smooth operating but not too sensitive. The supplied storage pouch is a great extra.
Summary: As stated in previous reviews, this works with Mac OSX Mavericks out of the box, but needs a little finagling to get the start and stop buttons to work. One of the highlighted reviews goes over that. This remote makes it incredibly easy to go through a presentation. Way way better than the little Apple remote since it doesn't require line of sight.
Summary: This presenter works well. Fits nicely in your hand and enables you to manage your presentation easily. Frankly, I have found the control you have over your presentation to be slightly addictive. The one hiccup was all my doing: it took me a bit to figure out where the wireless USB remote receiver was stored -- it nests in the large end of the presenter for easy storage and removal (the illustration in the almost wordless instructions didn't quite do it for me).
Summary: I bought this with my Christmas gift money from in-laws and i feel like the wisest investment for my graduate school study and my teaching assistant job. I let my professor use it when he gave a talk on a seminar. He used it the first time and said to the audience: every one of us should have one of this. I also used it for my first day class. It makes my presentation a lot easier and more professional.
