I didn't love it and took it off pretty quickly. I found it stingy and distracting but not in a good way. However I only used it after I was in a lot of pain. Something tells me if I had used it from the start and had the chance to get used to the sensation before my labour got intense it would have been more useful. I would try it again!
Yes the physio I hired ours from recommended putting it on from the first contractions.
