I have two daughters ages 4 and 6, I have read the other reviews about strings breaking and such. We had our sky dancer now for a year. At first my youngest did have trouble pulling the string, but once my oldest daughter and I showed her how to pull, she did not have any trouble. Camille flew wonderfully untill about a week ago when my cat developed a fetish for her wings. My suggestion to those parents thinking of buying one is this. My daughter is 4 and it took her a little while to understand how hard to pull this string. I don't recomend it for kids under 4. Also if you do have a cat you might want to put the doll up at night. I have given a 4 star rating on education for both hand eye coordination and control. I will be buying two more for christmas this year. Personally I think it's a great toy and a nice addition to a childs playthings.
