My friend recommended against it. She said it's really the labor thing that hurts and when you experience it, the pain from crowning to birth will be just a piece of cake. Can't personally say anything about it, though. I'm a CS mama!
I wish I didn't get one as it didn't work for me. It was a waste of money (for our part) because we paid for the epidural and the anesthesiologist but I still felt the pain until delivery including the episiotomy (and stitching).
