My iPhone is my alarm clock, so it ends up on the floor, across the room when I wake. But all you have to do to shut this "Magic" Sensor Alarm Clock up is wave.
Waving, however, could be a problem for this clock. Because it is buttonless, the only way to control all the settings and switch between the time, date and temperature settings is with motion sensors and gesture controls. I personally wouldn't want a clock that might turn off my alarm or change my settings every time I lifted my head to check the time in the middle of the night.
