My green cheek, Poppy, got her leg band stuck in this toy. Thankfully, her leg wasn't broken, but it scared her quite a lot and she twisted her leg in an uncomfortable way causing her to favor it all night. I'm glad it wasn't any worse.
There is a version of this toy that does not rotate, and I believe that one would be safe. The fact that this one moves can cause the bird to lose their footing and become injured. Even without a leg band, they could get a foot lodged between the sticks. In addition, they could get trapped between it and a wall or wedged against the ceiling depending on the placement of the toy.
I've also seen similar versions of this toy on other websites, some of them vendors from AA. I don't want to call any of them out because for the most part, they do a great job making sure that what they sell is safe for our fids. I just want to share that these toys in particular have the potential to be unsafe.
