Title: Button sticks... a big problem
Review: I purchased this product to be primarily used as a tool for advancing my classroom PowerPoint slideshows. At first, I loved my new freedom to move about the room while giving lectures. After a couple of weeks of gentle use, the advance button started to stick which causes the presentation to advance out of control to the end. I called customer service, and they kindly sent me a replacement. During the first day's use of my new pointer, the button stuck and a slideshow advanced out of control again.I will be looking for a different model. I suggest you do the same.
