I must admit that I'm glad I'm the grandmother of the 2 kids to whom I gave these Move2Play Kidz Bop Karaoke Microphones. My son's 2 daughters, girls ages 4 and 10, who both had November birthdays, were delighted with the microphones. The 4 year took a little more time to learn the features, volume control, echo, and music play. However, she watched her big sister "do things" with the mic and then caught on pretty quickly. The 10 year old is able to stream music from a tablet she has and likes being able to sing along with her favorites. She does dance routines (because she takes dance and gymnastics lessons) and narrates her performance or sings along. The rechargeable feature is great because I can't imagine how many batteries these kids might use. Why am I glad I'm the grandmother instead of the parent of these two performers? I couldn't stand the noise because the mics really sound like professional microphones. The girls love that!
