My 10 yo and 14 yo fell in love with this at the Great American Scrapbook Convention in Arlington, TX yesterday. Their favorite thing is the small round charms that are the perfect size to fit the Round 14 shapes and turn them into necklaces, earrings, or charm bracelets. They are using ribbon to thread through the charms to make the necklaces and bracelets.
I agree with the other review that it could get pricey to buy a new tool for each shape/size. I would love them to improve this so that it is a bit cheaper. And my girls are anxiously awaiting for some small heart shaped charms to make heart shaped jewlry.
