This product seems well made and is easy to inflate. I rated it with one star because it ruined the finish on a wooden dresser. I left the ball sitting on top of a dresser for several days, and something in the ball's composition reacted with the finish on the wooden dresser and caused the finish to bubble where it the ball was sitting.

These are great for PBT and very durable. The weird part was that every ball I got from them was a different size, not just because of how much it’s been pumped.

I purchased this after my Pilates instructor suggested it for some of our back exercises. I wish I had read more of the reviews. The tube used for inflating the ball is the same size as the straws that come with juice boxes. When you remove it to push in the plug, you lose a good amount of air. I have attached a picture of the directions that state "It takes special skill to add the plug quickly after inflating with the straw."

It is just the right size and strength for knee squeezing exercises and I don't need to worry about it breaking. I had a hard time initially blowing air into it until I realized that I needed to break through the rubber first. Then, it was easy to blow up and plug. This is a very good exercise ball.

I initially purchased this ball for my home Barre workouts, and it works perfectly for it. But when I was working out, my kids kept trying to swipe the ball to play with it - and it is a great play ball too! It's soft enough that they can't hurt each other with it but sturdy enough that they won't pop it. I ended up buying a second ball so they could play with one while I work out, and it has provided hours of entertainment.As far as inflation goes, it come with a simple "inflation kit." Basically, it's a hard straw and a plug for the ball. But it is simple enough to use. Insert the straw in the hole. Blow up the ball. Plug the end of the straw with your finger while you get the plug ready in the other hand. Quickly pull out the straw and insert the plug. It's not complicated, and I lost almost no air while inflating the ball, so I am very happy with the firmness.

Sturdiness from 1-10 = Zero‼️ It isn’t safe to use. I’m by no means with extra pounds, and even for me it feels extremely weak to use for weighted purposes. So I’ll keep for somewhat-deflated support for lower-back towards coccyx plus to show to one of my IMA (Internal Martial Arts) client how she can protect that area when doing match stretches because she’s quite slim and tall and that particular area always hurts her. She’s in her 60s, and for sure remain quite an active woman. Thus the ball in itself can perhaps serve for this extra back support. If you want it to place your full weight on it, I would recommend getting a much tougher one to be safe plus the air holder on this one does stick out — painful to imagine getting in one’s eyes or any sensitive area of one’s body. So keep that in mind plus the fact that it takes several minutes to finally take a well suited round shape. Bottom line, far from perfect, and when it comes to something that will come into direct contact with our body, it should be a lot safer and sturdy!Note: Keep in mind that mine may have turned out that way, and that the company may do better in others — do not know — but leaving room to be less “harsh” toward a company which may have dropped the ball this one time … who knows!— I chose the gray one to match with a much bigger one at I’ve at the studio.

I have several balls to use with my exercises This ball is my favorite. It is bouncy, yet sturdy, making it quite versatile. It has a great texture that lets me grip it without it being so sticky that it picks up dirt and lint. The ball is the best size for me to use with my back and to do my chest squeezes. It is perfect for my needs in every way. I cannot think of anything I do not like about it. It is definitely great quality for a good price.

This is the best exercise ball I ever bought. It came with a simple inflating kit. The instructions that were included said the straw would “provide amusement while inflating”. It did indeed. It only took me two tries to properly replace the plug. It is strong and secure and feels that it will withstand a good workout.

I bought this to use with a workout dvd that needed a mini stability ball. I've been quite amazed at the difference it makes to core workouts, your muscles have to work so much harder to keep steady on the ball. My abs were seriously shaking, in a good way, and normal crunches seem rather tame now by comparison. It's also wonderful because it supports my back so I can do these burning exercises without hurting my back. I've found other uses too such as squeezing it between my knees to work the inner thighs. It's incredibly versatile and can open up a whole new world of workouts. It comes with a straw so you have to blow it up, which doesn't sound very fun, thankfully I had a pump from my full size stability ball which did it in minutes, but without a pump be prepared for some effort inflating it. It's strong and air doesn't leak out even when leaning right back onto it. Incredibly useful and versatile workout gool.

I bought this on the recommend of my Pilates instructor. It's really helping me with my exercising and feels sturdy enough for me. I've never used one of these before, so wasn't really sure what to expect, but it seems to be helping to firm up my thighs, which is what I wanted.

I bought 1 ball previously and was happy with my purchase then I bought another one so I have 2. The new one was 27cm although it is supposed to be 23cm like the previous ball. I sent it back and re-ordered just incase it was an error. The new one that came was also 27cm when it was supposed to be 23cm and it didn't even come in the correct colour I ordered. I will not buy this product again!!! (Light blue- old , dark blue- new)

I was worried I would have to buy a pump to inflate this, but it comes with an easy tool to inflate it yourself (a straw that you blow through) and a plug that has stayed in place well (you also get a few extra plugs, just in case). I have rolled around on this regularly, and it has stood up to use well.

Bought a load of these for Pilates classes. They seem thicker and sturdier than other small balls i have used. IN addition they were easy enough to blow up and the texture gives a nice grip. Definitely recommend these!
