Mini Exercise Ball, 9 Inch Small Gym Ball with Inflatable Straw for Yoga, Pilates, Stability, Barre, Physical Therapy, Stretching and Core Training, Improves Balance, Strength

Serves the purpose. I got what I was expecting. Really good. Easy to blow as well. Not as difficult as how people mentioned in other reviews.

جودة سيئة. أنبوب النفخ أصغر من الفتحة، مهما نفخت فيها ما تنتفخ للحد الأقصى والهوا يطلع على بال ما تسكرها. فعلياً تنفخ بقربة مشقوقة

Great ball, thick, pink and light weight. Great for my palliates, and for taking on holiday.

The plastic straw sent to inflate the ball is too big to fit into the valve so you can't blow it up.

This ball comes with a little straw to inflate it, making it extremely simple to use. However, it's quite difficult to keep all of the air you pump in to inflate it from escaping as you try to enter the plug. I've been re-trying it on and off for a few days and have now filled it to the point where the ball doesn't appear sagging. I'd still like it to be more full, and I'll probably keep trying to get more air into it. I made a bigger yoga ball out of a straw and a hand-pump I had laying around. My problem isn't obtaining enough air in the ball; it's how much air is wasted in the little period of time it takes to insert the plug. This was purchased for physical treatment with a neck injury. It is necessary for me to keep the ball between my head and the wall. I then roll/move over the wall while rotating my head. After 5 minutes, I discovered that the red ball had left tiny markings on my white wall. If I keep doing this, I'll be able to see it.

This is exactly the size I needed to do my exercises for hip abductor tendonitis! Easy to inflate with included straw. Would buy again.
