I purchased this to replicate physical therapy exercises for my shoulder after surgery.Looked and weighed exactly the same as my therapy ball. I was expecting something a bit more "ball like" with a touch of "bounce". The therapist has me gently bounce this off the wall from a distance of about six inches. This ball has no rebound to bounce at all. Other than that the quality is perfectly fine. Arrived quickly and well packaged. Just did not suit my needs.

it is softer than i expected

Sand is loose in the ball, makes it awkward for tossing to a partner or moving around for yoga poses.

I bought this fitness ball to use as a neck massager of sorts. My friend suffers from migraines, as I do, and she was told by a professional to lay with a ball like this under her neck until her tight muscles released. I have tried this with her fitness ball and it works great, so I bought this with the same purpose in mind. This ball is bigger is circumference than what I had hoped for and is not tightly packed. I needed it to be tightly packed in order to use it for what I had in mind. I released some air from it, but it doesn't do the trick. I'm sure it's great for exercise, as that is what it was made for. The ball itself seems to be good quality.

Okay. doesn't hold the extra air needed to keep it rounded along with the sand inside. Need to pump air in fairly often.

Good quality but overpriced
