Review on Rechargeable KENGDUDU Digital Stylus Pens for Touch Screens - Fine Point 1.5mm Active Smart Pencil, Stylish and Compatible with iPad, iPhone, Tablets (Milky White) by Jay Lee

When I first got this pen it worked decently. We will not deceive ourselves here. It's not perfect, but it was good enough for whiteboard drawing to work. But after a few months, the sensitivity got worse and worse, and now it's almost impossible to use it. I wouldn't recommend it to anyone who wants to draw with it or even create a virtual whiteboard.
