I offered the walkie talkie to my 5 year old son for Christmas, at first he spanked his head because no superhero image or other. But after the first use, he was happy, one hears the voices perfectly without sizzle. I have very thick walls in my house and so I wanted something simple to use and function well malgrès my old house .. My son play with his sister, 9 years old, who is also happy to play with these walkie talkie .
