Review on RaySoar Ultra Bright Mini LED Keychain Flashlight (Pack of 7) - White Light with 7 Colors Shell by Robert Hole

>. They come with a split ring that can be added to a keychain or used as a keychain. They are easy to activate (press = turn on; release = turn off) and have a slide lock to keep the light on. Very useful for getting the right key and getting that key in the keyhole.>. When we go camping we give each kid a BRIGHT ORANGE whistling lanyard and one of those flashlights [they get really bored turning the lights on and off]. we try not to lose sight of them, but there are stories. . . We whistle ourselves when it is time to gather [food etc.]. Kids don't worry too much about the dark if they have a light that turns on when they want it. [We don't let them turn on the lights at night.]>. Batteries are interchangeable, cheap. BUT you need very small screwdrivers to open the case, which is what we do at home. The light requires TWO BATTERIES.
