I said that i regret bying mouse4d,but after more days of use i begin to appreciate it:smooth move on the tablet,precise and more speedy buttons than my logitech.I like very much its thumbwheel .Still buggy when i use with Deep Paint which it suppose to support mouse 4d.Still sometime seems stopping a fraction of second on the screen.This mouse not replace the pen for drawing but as mouse,i can say now i like it.Need Intuos tablet for using mouse 4d.Note that this mouse 4d is very different than the one coming with Graphire tablet
