I purchased several of these presenters to use at our agency. I made my decision primarily based on the reputation of Microsoft. When I first received the product, I was pleased. It has a good weight, feels like a quality product and is easy to use. HOWEVER, after only a few uses we found the USB component to be a total waste of money. It breaks easily and then the presenter will not communicate with the PC. We basically have 4 over-priced laser pointers because the USB portion of the devices broke. I must add that the equipment wasn't abused or mishandled. The USB portion is just fragile.
