Mini Exercise Ball 9” – Small Pilates & Yoga Stability Ball for Core Strength, Balance, Pregnancy & Physical Therapy – Anti-Burst Swiss Ball w/Quick Pump – Home, Office, Gym

I like the material, the durability, size and there was no yucky smell. I found it super easy to blow up, took me less than a minute and it came with extra plugs which is nice. I like that it's black and now I can start doing the ab exercises that were too hard for me without some support. It's comfortable and cushy and I also like using it as a neck pillow when I'm laying on the floor doing stretches on my half foam roller and whatnot. So glad I snatched this up on sale.

It comes folded up, has several plugs for the ball (there's only one opening), and an Inflation Straw. Remove the Plug in the Ball, Insert the Inflation Straw, Blow up the Ball as desired and needed, cover the straw with a finger when removed from the mouth, or cover the opening in the Ball with a finger once straw is removed, have the Plug ready when the Straw is removed from the Ball, and insert Plug into Ball. It worked fine for me. I was told to buy a Ball or use roll up towels, the Ball is easily preferable. I put the Ball between my legs and squeeze somewhat, hold for 3 seconds, release enough to take the force off the Ball but not enough to let it drop to the floor, and repeat for the the specified Repetitions. I am happy with the Product, it works as advertised, seems durable, and suits my needs fully.

I never thought I would have to blow up this ball by mouth. Lost a little air removing the straw and inserting the plug. There has to be an easier way.

This exercise ball is great for at home Pilates! I was looking for a ball that is much smaller and lighter when it comes to doing strength training. It was easy to pump up and fast. My only main concern is that it deflated very quickly and I had to always re-pump it back up every week.

My previous Theraband Mini Ball met an untimely end thanks to my dog, which led me to try this alternative. I actually prefer this new brand significantly. The ball's superior, smoother texture offers a much more supportive experience, particularly during core workouts. Very durable.

It's easy to inflate and get the plug in. I use it for physical therapy for my knee replacement and it's worked beautifully.

Waste of money. Very disappointing. Will be returning if possible. I am not sure how this product ever got any good reviews. As many other reviews mention, this ball doesn't retain air! This is mainly because it's hard to put the plastic stopper in place in time to trap the air. I tried blowing it up with my own lung power and with an electric air pump - both times I could get the ball to an appropriate firmess, but it would immediately deflate significantly no matter how quickly I put the plastic stopper in place. The air hole needs to have some sort of valve in place to create a better seal and trap escaping air. It also was unclear how firm the ball should really be when fully inflated. Some of the illustrations enclosed showed the ball as an oval when performing exercises - presumably under the weight of the person - but I was seeking a firm ball like a normal semi-rigid yoga ball that would maintain a circle - for rounded support with weight on it. This ball doesn't seem capable of that, it becomes oval and misshapen quickly. It also deflated completely when left for 8 hours so it would need to be blown up each time it is used. The description says it can support 600 lbs, but I didn't dare put even my full 140 lbs on it, because it seemed like the plastic stopper would pop out with any pressure and instantly deflate and cause injury to anyone applying weight to it. Horrible product.

So far this has worked for what I need but I tend to have to pump it up each time I use it. I can’t get it to keep air in all the time. It doesn’t completely deflate between uses but it get a little flatter than what I would like. It is good quality but has that flaw.
