Rhapsodia may look harmless and normal on the product page, but this toy is anything but ordinary. There are three balls, each one larger than the one before it. The largest ball is pretty big, so beginners beware. Each ball has its own inner weighted ball, and they jiggle about when inside of you. I would compare this feeling to the sensation of a vaginal kegel exercisor. The adorable heart base design leaves a little to be desired when it comes to anal safety, but I have not had any problems so far.
