Summary: I've neaver used any of the powerpoint or any real application that this product was meant for. My computer monitor IS my TV so the problem was trying to "mouse" on my knee or the arm of the armchair. This product was a wonderful find. It was able to duplicate all of the functions that a normal mouse does. It also functions with my media player to control volume and tracks and stuff.
Pros: Uses i lithium battery. Has all mouse functions.
Cons: May be difficult for a left handed person to drag and drop. But all other buttons are ok for a lefty. It takes about a month to get used to it (you have to learn new key locations)
