This set is great! I got one as a girl, and parts of another in a lot.
The crutches very realistic, they look and feel just like real crutches. Real metal crutches are not lightweight so I felt like the weight compared to the dolls was pretty realistic too. To get them to stand on the crutches I usually have them stand up first, then pull one foot out like they are walking and put the crutches under their arms to support the weight of the foot that's out. It takes a little extra time but it's possible. They work great for play too. The cast is cute and I haven't had a problem with its fit, maybe a little big on the newer dolls but not noticeably. The inside feels like a human cast would. The paper doll is a replica of the old ones found in the AG Mag which I thought was neat when I was a girl. The spinning toy really works and is very fun to play with. It came with stickers to put on the sides of the spinning part. The tic-tac-toe game also works. I remember my friend's dolls would play my dolls at it I'm also impressed with the water bottle/thermos because it has the soup cup lid and the regular lid like a real one.
All in all I'm really impressed with this set and it got a ton of play when I was younger and I still use them quite frequently. I use the thermos as a water bottle when the girls go camping. Everything is very realistic/actually works.
