I purchased two of these for my 6 1/2 year old twin granddaughters. They were enthusiastic but the quality of the string provided put a damper on their initial response. I think others have noted disappointment also about the fact that the string is NOT elastic. A little stretchy quality would have allowed the girls to move their fingers without dropping the string and having to start all of over again. Would have been better for grandma and mom, too, who were helping with the demonstrations. Still, one of the twins persevered and was proud to achieve the witch's broom which she has subsequently done again and again. . .even with her eyes closed.
