I searched all over the internet for remotes that could be used with PowerPoint after my old one became obsolete. I compared price and functionality of many different devices, and gave this one a shot. I was glad I did. I teach at a high school and use PowerPoint for 5 hours a day as a way to lecture, and this works great. The mouse function is easy to use, and the slide advance/retreat button on the side works great. The plug and play capablility makes it extremely portable. The battery hasn't died on me yet, and I've used it about 20-25 hours/week for the past six months. AWESOME PRODUCT!!
