I have one, too. The rockered type, wooden by HolySalchow. It's OK. I need to do more practice on it, but the reality is, I get too dizzy. I've always had dizziness issues, even when I was a kid, but now as an adult, one good spin on that thing, and I'm nauseated for the rest of the day. On ice, it's not quite as bad.
I'm not sure what the difference is, since I can't do nearly as many revolutions on the trainer as I can on ice. But the dizziness has certainly curtailed my usage.
Hopefully this is irrelevant to your daughter, but might be something to keep in mind. The HS spinner is a little cheaper than the comparable Edea one. If you mine these forums, you'll find some exercises for it, especially in the threads titled "spin trainer" or similar. But probably a conversation with her coach would be more fruitful. It probably helps to at least start under a watchful, and knowledgeable, eye.
