I think these are overpriced. I got these for the kegel benefits, but I don't really understand the point... They are weighted and you're supposed to use the light balls first to strengthen your muscles... How do these fall out? I feel like they get stuck! And I cannot feel any kind of vibrations at all when I move, I even jumped up and down... You can feel them as much as a tampon, which you can't feel at all... Just a little disappointed...
