These walkie talkies for kids are really clear, and totally fun for the kids and even the adults. The two way radio has a long distance range so they can go to the end of the house and still talki to each other. Takes batteries and once batteries are in place it is really easy to set up and start using. The kids love them and even us adults tried them out and liked the way they sounded, very crisp clean sounding. These make it reall easy to keep track of everyone. They are good sturdy and made very well.
