Summary: I am a technical instructor, giving over 200 presentations a year. I bought this product over a year ago so that I could reduce the amount of gear I had to carry when traveling (mouse and presenter). The presentation function works pretty well; the only problems I have experienced is the occasional loss of signal between the presenter and the base, and a rare "faded" laser pointer (difficult to see from the back of the room). The mouse on the other hand is horrible.
Summary: Very nice to look at, well-designed and good reviews. I think I just had a bit of bad luck with the one I was sent. Returned it and tried a different product which did the job and was cheaper, but not as nice or as high quality. Would certainly consider this one again.
