V.B.
meh.... I had a hand-me-down one as a kid. It was lame. I gave one to my niece about 15 years ago when she was about 7, it was just as lame.
My daughter (now 12) has never had one, and if she wants to bake, she does it in my kitchen in the real oven with real food we can all enjoy.
I'd say skip it.
Get her one of those rubber band loom kits instead. They are ALL the rage right now.. and very age appropriate. :)
