I bought this set for my 4 year old granddaughter. I bought a larger set for the boys and was a little concerned that she might feel left out. To my pleasant surprise, these phones were perfect for smaller hands, well built and had excellent reception. Can't comment on the battery life yet, but I bet it'll be good. Big hit at Christmas! It's fun teaching her "For" "How old are you 20?". Next year we might switch to Morse code. Finding fun ways to connect with those precious grandchildren is great.
