Bought this back in 2012, and it's pretty much the same as it was back then. Easy to inflate and holds the air for a long time. I've only had to reinflate it once during this entire time.

I bought the 75 cm ball and I've used it for a few months now, the ball has maintained it's proper size and pressure and functions as a situp ball only for me. It seems well made and will last for years. The only problem with it is the cheaply made, useless pump that they included would take days to pump up, so I used my electric air pump to do the job. Remember to pump it up about 80% then let it sit for 24 hours, then pump it up to the correct size ( they provide a tape measure to check). If you don't do it this way it will form an egg shape and won't be round. This is key.

I'm writing this review to pay my respects to this remarkable ball, on which I am presently sitting as I write. I bought the GoFit 75cm commercial grade Pro Ball literally TEN YEARS AGO. It has traveled with me across three states, two degrees, and a decade of life, and it still holds my 190 lbs without leaking any air. I filled it with air when I moved into my last apartment, and after two years of use it was still fully inflated. I suspect that they will soon uncover a hidden chamber in the pyramids, and inside there will be one of these balls, still inflated and usable from 3000 years ago...

Had one of these brands for 10 years before my kids busted it. I bought a different brand ball and it lasted all of 2 weeks. Bought this brand again and should have from the start. Material is thicker than the other balls, and it's made to last. No complaints at all.

It feels very sturdy, and after the first week or so, I haven't needed to add any more air (~4 months, if not longer). The excercises on the ball itself are nice - you don't need to consult a booklet when you want a spontaneous workout.

It Popped

the ball popped when i jumped on it. and it scarred my cat to death

Exactly What I Wanted

I wish I had made this purchase sooner! It is exactly what I needed. Shipped quickly, comes with a hand pump and was easy to inflate. The DVD that comes with it is super helpful. In addition to the accompanying instructional dvd, it makes a great desk chair, offering further opportunities to increase core strength! Great buy!

High Quality

I'm glad I went with the higher quality ball. I'm using at as a desk chair for a raised surface, so the size is perfect. The ball seems very durable, and doesn't lose inflation.

This Product Works

This ball is actually 75cm not like some other advertised balls. It is well made and has not deflated. I am using it for an office chair and is working great

Great For The Whole Office

Bought 6 for some of the office staff and they love it. Now almost everyone wants one to replace their office chairs. A happy office is a happy company.

Exceeded Expectations

First time I've purchased one of these so wasn't certain what all would be included...hence, I was very pleased to see a pump! Along with the DVD and what I will refer to, it's "Workout Ring", I am super happy with this product. What's a "Workout Ring"? These guys printed basic visual cue's to several of the possible stretches/ exercises you can perform with the ball, on the ball...it's very helpful as you become familiar with your new stability ball. Enjoy!!

Getting On The Ball

as someone who sits at a desk a lot or on a plane, I got this to replace my desk chair and improve the tone of my mid core

I purchased this ball to replace a different one that I had less luck with. I was hoping that the "commercial grade" would yield better quality results. Here are my initial impressions. If things change over the next few weeks, I'll be sure to leave an update.ContentThe ball came with a useful starter booklet describing basic exercises (that are also printed around the center of the ball), a DVD that I have not looked at yet, two plugs, a plug removing tool, a premarked tape measure with holes for the pump, a pump, and extra nozzle for the pump, and the ball. Definitely a superior initial impression over the other ball I received.Initial Quality ImpressionThe ball felt heavier than the other one I had received, which was also rated for 2000 lbs, and didn't smell particularly bad. Indeed, pumping did seem more cumbersome. Others have reported that the included pump is cheap and fairly worthless. I never even tried it as it was identical to the lousy pump I had received with another product, but instead used the handy-dandy included nozzle that fit nicely into a bicycle pump.The instructions said to pump the ball up over 2 days, half the first day, then let it settle for 10-12 hours before finishing the job. I followed the instructions with some disappointment in not being able to put the ball to immediate use. After pumping the ball fully using the handy included tape measure, I found that it was a bit softer than the other 75 cm ball I had, despite the extra effort it took to actually inflate the thing. However, it is not soft to the point of sagging, and can definitely be used as is. Note that I am not any kind of an expert on these things and it may be that it is supposed to be a little soft. I am simply comparing it to a previous product I had.The pin remover worked well.Overall, my initial impressions are very positive. I considered giving it four starts instead of five due to the lousy pump and the slightly soft feeling, but I think the extras that came with the ball more than made up for that.**UPDATE**I've had it for 20 days now and it has not lost any air. It's still a bit soft, but I think that's actually okay.The DVD included is actually quite helpful. Includes both basic and advanced exercises. I would definitely recommend this product.**UPDATE 1 YEAR LATER**I'm amazed. The ball is still in good shape. While I no longer use it every day, this is definitely a solid product. It continues to hold its shape and has lost very little air. I would strongly recommend this product.

I just pumped this ball up all by myself with minimal effort, using the plastic pump that came free with the ball. A bunch of reviewers seem to feel this is too much trouble... people, it's an EXERCISE BALL! Work those flabby arms and pump it up yourself! It does not "take forever" .... it took me about seven minutes of continuous pumping, switching arms, and gave me a great workout. I am sitting on this ball as I type, it inflated fully without issue. Save your money and work those arms out.

I got this ball several days ago and I consider it a great ball at a very reasonable price. It is attractive (looks just like the picture), feels good on the skin, is made from very sturdy material (definitely professional quality) and didn't have any odor right from the start. It really measures 75 cm in diameter. I found that the best way to pump up this ball is to use a compressor to get a good shape and then switch to the supplied pump to top off at high pressure. Unlike some other reviewers, I found the pump to be excellent. It is obviously designed to deliver small amounts of air at high pressure so I was able to get a very firm ball in short order. It pumps on both the upward motion and the downward motion which is a very intelligent and useful design. However, it would take a long time to fill the ball completely using only the supplied pump. When I bought the ball it was not advertised to come with a DVD so make sure you check on that first before ordering. I'm 6'3' and 220lbs and this ball is the right size for me for general exercising. I can use this ball all day long and it will last forever.
