My 4000 mouse with the v2 transceiver works fine with Intellipoint, but the v1 one does not, and I haven't found a solution. Very disappointing MS software / hardware won't even work together. Since I'm running this on WinXP, I doubt MS support would help me with this problem.
Works on most surfaces; Batteries life seems ok to me; I turn off the power switch when I'm not at my computer; The magnify feature is one of the main reasons I buy / like / use these mice
Rubber on scroll wheel can disintegrate after awhile; Tried storing transceiver in mouse once and needed a pliers to remove it; I'm having a problem with Intellipoint software not recognizing the v1 nano transceiver on this mouse and my 3500 mobile mouse also, so no button customization is possible...
