Bought this to replace my misplaced Pogo stylus.
It has a very "spongey" tip so that you need to apply very little pressure. When scrolling it feels exactly the same as using your finger tip, minus the finger marks. Harder tipped styluses (styli) are not so good for scrolling gestures.
Also, being thinner than a finger, you have a better view of what you are doing when selecting text.
