I needed a smart pen to draw and take notes and it worked great. He is smart and elegant. The kit included spare tips and a battery. Best of all, when I put my hand on the screen, it doesn't register. While it works in all Microsoft Office applications. It even takes into account how hard you press to create thin or thick lines. After installing the battery everything worked. I was looking for something cheaper but it was definitely better than Bamboo or HP. Highly recommended!
