These are great! I had bought a different brand years ago … These are great! I had bought a different brand years ago which were supposed to be good for 25 miles, but they only worked if there was nothing in between the two walkies. These work amazing, allowing my 11 yr old son some freedom to wander around the small town where my parents live during his summer vacation there. He loves them!
