I bought one and it's my DGD favorite thing in my whole sewing room. She winds bobbins while I sew. She feels good knowing she is really helping do something. I buy the plastic bobbins at WalMart, buy the $1 spool thread and she has a blast filling them. We use the filled bobbins at guild for basting quilt tops, whatever. I use it to wind extra bobbins for my machine to keep in my sewing tote for workshops and classes. It has been worth the cost just to have DGD enjoy it. I have a plastic bin full of filled bobbins though. :lol: :lol: :lol: :lol:
