I love them so much I bought them as a birthday present for a child and tried them out Pair for us adults! They are cool! The range is very good and the battery takes 4 hours but lasted 8 hours inside and outside of the zoo day. Children couldn't stop playing with them except for dinner and bedtime. After reading the instructions, using it is quite easy. Outside of the package, they're a little tricky to navigate. I'd say if you're buying these for kids they probably need to be able to read or have the patience to have someone show them how to use them. The girls we gave them to were a bit young to learn how to hold buttons (3 and 5 years old) but they just loved listening to their sister on the other end of the line. The 7 year old did great! I would say that the quality of this product is very good. I would definitely recommend it!
