Negative Positive
Title: Worthless
Review: This item only be used within a limited range, basically within caretaker eyesight. In other words, if you cannot see your child then s/he is already beyond the range of this gadget. I have tried it at the playground and at the beach, it was totally useless with my toddler. Mine did not work for a distance of 150 feet. More like 50 to 75 feet.
