This device sits in one spot. It doesn't matter what surface is used on...I can lay back in a recliner and have this controller comfortably sitting on my chest and do everything I need and do it better and easier than with a standard mouse. The ball is thumb-controlled and the whole thing fits the hand like a glove. The software lets you assign buttons and make custom adjustments to suit your individual needs as to how the pointer moves, how fast, how far, etc. I have bought many of these for myself and as gifts. It will take a little practice to get the feel of the controller but once you do, nothing else compares. I am not associated with Logitech in any way. I'm simply a very satisfied user and customer. To make this an even better controller I would like to see the addition of a tilting wheel function to scroll pages right and left.
