Query: Attention Doulas! Great as a birthing ball!!

As a Birth Doula I purchased this ball to test it out before I reccommended it to my clients to use as a birth ball. It was easy to blow up with the hand pump provided; it only took about 20 minutes (following the overnight directions) your arms get a bit of a workout! I have had friends and family using it and not being exactly gentle! It has held up well. I reccommend following the height guidelines when you purchase your ball. I have all three sizes and they really are for the heights they reccommend. I think this is a good product if your looking for an exercise ball or a birth ball.
