Fastpitch spin trainer for daughter

[Bassinhunter]

Does anyone have recommendations for spin trainers pitchers use?? I want to get my daughter something she can practice spin with but want opinions good and bad on which ones work the best

I like some would say nothing is better than the ball. Learn the correct way to spin, then practice. Practice, practice, practice. Then practice some more!

javasource has a pretty good slide presentation that explains how useless most of these devices are.

Practice!
