I have one. Had problems with it - but apparently it's just me - but read the instructions very carefully to avoid injuring yourself.

I think i paid about $160 for it, apparently they are supposed to be great, and will def. use it b4 next birth. You can also use it for pelvic floor training, so have been meaning to start using it now to help with that.

You can get it online, i got it from a pharmacy in Clayton, Vic.
