hi ladies. has anyone had an experience with a pelvic toner machine? I'm considering investing one but I'm torn between two, either the Pelvitone or the pelvictoner (ones an electrical stimulant and the other looks like straighteners that you insert and squeeze). I've suffered for years so I'm deffo investing in one ready for after childbirth, as me squeezing just does not work for me.
