Working great on my D3. Had to clear data, uninstall, reboot, reinstall, reboot, then open app to get it to work correctly but after all of this I couldn't be happier.
You won't be disappointed. I am much happier with this than the X2 for sure. There is really no comparison and to me the D3 proves that the X2 was rushed. The D3 is truly a worth successor of the D1 and D2's.
