It will light you the way to your destination, then turn off automatically after 15 seconds of no motion when you return to bed.
You could put it in the bathroom where it is most needed, just inside your main entry door to light your way when returning after dark, or under a cabinet if you sneak out for a cookie at three AM.
Put it on a table top or mount it on the wall. You can remove it from the wall bracket to use as a flashlight. It uses three AA batteries.
You can find the NightMinder at Amazon.com for about $16 (as of April, 2016).
