Family member got walkie talkies for the kids age 6 and 5. I was sceptical about the safety of them but they convinced me they were safe. Just tried them out and straight away heard a man saying hello on the other end. Turned them off and put them back in the box. Don't think it's safe for kids to be talking to strangers or for people to be listening to their conversations. Is it unreasonable to give them back to the gifter? I know they weren't cheap and we won't be using them again.
