The Cosmonaut: Wide-Grip Stylus for Capacitive Touch Screens is out of this world or at least it looks that way since it resembles a rocket in the box.
This stylus is compatible with all capacitive touch screens, like the iPad, iPhone, Kindle Fire and more. It will also work with any app. Use it for sketching, and writing and more. It is made durable so it will last and it is designed to feel like a dry erase marker, because drawing on a tablet is like drawing on a whiteboard.
The tip is said to be very responsive and smooth. It is only $25. from Amazon.
