I bought a 26' (65cm) blue ball. Inflating it took at least a half hour. I could see when the air put it into a round form, it seemed too small but was pretty firm. After inflating to the point of arm exhaustion the ball only inflated to a bit beyond 24" from a lot of pumping. It was so firm at 20", I was very cautious to add more air but I managed to get it to around 24". I don't know if it would expand to 26" but by the way it was expanding, it obvious would take another 30 minutes of pumping to enlarge to spec.. The more firm the ball, the slower it will continue to expand (pressure is not linear). The box and ball are clearly marked for 65cm. No mistake there. My suggestion to the manufacturer/seller would be to have some more details about pumping up the ball such as how it expands and how firm it should be at full pressure. My worry was it bursting in my face. This is my first ball of this size. We see how it holds up from use.

The ball seems good. Bought it for my wife and she likes it. The pump seemed pretty cheap so I used an air compressor to fill it up but it seemed like it would have worked.

Loved this ball while pregnant.. it gave me so much relief from all the exercises I could do with it. Easy to inflate & deflate.

Easy to inflate and holds air well. I have not had to add more. The only downside is that it still has shipping ’wrinkles’ that haven’t smoothed out. It’s just cosmetic, but it still annoys me a little.

It’s perfect it’s easy to inflate but it does take a few minutes depending on what size you get we got 34in cause I’m so tall so it was really big I love it super comfy and definitely works definitely recommend for anyone that needs this or wants it for there pregnancy it also is really firm so strong. 🤰🏻

It looks and feels just like the much more expensive ball I use in my workouts at the center where I've gotten PT. We'll see if it holds up!

Bought to use both for stretching and to sit at a desk. Did take a couple of days to inflate (inflate 80% and then waited 48 hours to fully inflate). Doesn't feel as sturdy as our Gaiam ball we had for 8 years which finally popped. But for the price, does the job

It was great for her back pain and one way to move and exercise as well

We bought 35 of these balls for our office in November and December last year, as they were described as suitable for using as sitting balls. However, less than six months later, five of these have burst. Three burst whilst people were sitting on them, and two burst spontaneously. We followed the instructions and did not overflate them, nor did we sit on them continuously throughout the day.Originally, we were happy with our purchases, as they were as described and arrived punctually. However, they are not durable, nor particularly safe. We have had to ban them from our office, due to the health and safety risk of any more bursting. Luckily, no-one has been injured so far.If someone was to buy one, then I would recommend that they only use it very occasionally and definitely not for sitting / weight-bearing.We spent around £700 on these balls, so unfortunately for us this was a waste of money. Take care when using.

Just received and inflated the gym ball to find multiple defects within its surface! They look like black scratches and mottling so looks old rather than a new unmarked gym ball. Looks like they could be a manufacturing issues. Looks like these could also be seconds sold as perfect gym balls so buyer beware. I suspect the ball isn’t completely round as it wants to travel when placed on the floor in certain positions so be prepared for the extra work out retrieving it!

I recently received my Excercise Ball, I bought the Silver 55 '' size.The looks great, easy to use the pump which is included In the box. Once it's fully inflated, the Excercise Ballseems strong. I already had bought the 45 '' Excercise ball from Urbnfit a few months ago, Which I found to be very good. I find the two balls, great for my home gym workouts.

Unfortunately waited to long to actually blow to ball up before realising it's far to small. I'm 5ft 3 so ordered the 55cm ball however it seems to be tiny, my knees are way up above the level of my hips which is the incorrect posture for use of a birthing ball & I do not have long legs in the slightest, can't contact the seller to see about exchanging or returning. Unfortunate because the ball itself is solid and good quality.

I’m 35 weeks pregnant and thought I’d treat myself to a ball. This has helped my back considerably as I’ve been struggling with sciatica. Can’t wait to use it in labour too! Really comfortable to sit and bounce on. Feels really safe and sturdy.
