Bests & Worsts Reviews from Amazon

We probably use these differently than most folks. I slip one into the pocket of each child when we're going out to busy places. When they wander off a little too far or I can't see them directly, I push the button coordinated with their color, and they know to start looking out for Mom. We took them to a busy Llama show (yep!) and the kids were able to hear their beepers over the llama hub bub when needed. Seemed to work from as far away as several hundred feet inside a large auditorium area.
