I am having consistent issues with the connection I think probably to the program. THe keyboard and the mouse connect and work great. I have modified/altered the buttons on the mouse, and those seem to fall to the way side or "reset" back to default settings. I then have to open the program, however it never loads. I am required to uninstall and re-install the Logi+ options program in order to reset the buttons I have saved to my profile. Once I've done that it seems to work well, however it falls off. I'm using iOS, not sure if that makes a difference.
