My 10 year old ordered one of these for herself, with her own money. The thing works but is tiny. She was somewhat disappointed.This is not the product I was imagining. This is made with the cheapest plastic and not at all sturdy like the ones I used as a kid. I knew it was not going to great craftsmanship, but I thought it would be better than this.Not going to use it, it’s embarrassing.
