I like it, it has 5 DPI settings that you get clicking that button behind the scroll wheel, 800, 1200, 1600, 2000, 2400.
My laptop is a touch screen and that came with a pen to use on the monitor, you can use it as a tablet.
I'm finding it very responsive and it feels nice in the hand to work with. Will have to wait and see how long it lasts before a re-charge is needed, I switched it off last night when I shut down for the night but left the receiver plugged in.
