Myself: Update: The first ball randomly developed a small tear in it after 2 months. I contacted Mantra, and they gave me no trouble replacing the ball, were prompt in responses, and communicated clearly with me.

The new ball is much more spherical, not the lopsided shape the first one was. It's doing great so far. I expect it to do better because it doesn't have the obvious issues the first one did. I suspect this is more representative of the product.
I'm still using my original stabilizing ring, though it has some bulges. I tried to reduce the air pressure inside it because I didn't want to risk a rupture in it too, but that made it too soft and less effective. I reinflated it back to be much stiffer, and it works much better. Still no problems from it. I suspect it may be from the same batch of rubber that was just a bit off, but it's holding up so far, and I have a backup from the replacement they provided me.

They had me re-order the same kit from Amazon for my replacement, instead of any direct shipping. But they were true to their word and immediately refunded me. I think I actually got my refund before the new kit, and the new kit arrived in 1 or 2...

mercuryval: This type of chair/ball was recommended by a friend, who also has one. I purchased it because I am working from home, sitting for long periods of time. I am a teacher, so I need something stable (so I don't slide around in front of the camera--lol) but also something comfortable. I have 3 desk chairs at my house, but I wasn't happy sitting in any of them for long periods of time. As a teacher, I am used to walking around for most of the day, and I prefer that to sitting.

This ball is perfect. I like that I can inflate it to the desired level of firmness. I followed the directions and inflated it in installments. So far, for the first few weeks, I notice that I need to add air every few days. This is not a problem. The chair comes with this little plastic tool that makes it easy to take the plug out, and the pump that came with it is super easy to use.

Stability is good. It generally sits inside the inflatable ring it came with. I do like to kind of roll back and forth between classes or between grading, so I'm sure if I were just sitting still it would be a little more stable. In rolling back and forth, I am able to roll out of the inflatable ring, though I suppose I...

M. Durkin: For the most part, this is a good quality product. That does not apply to the foot pump, which is horrible quality and essentially useless. The valves pop off, the hose pops off, the pump has a cheap plastic feel to it that you just know is going to break.

The exercise ball itself has a very good quality feel to it. The stability base is also an inflatable base, which I was not expecting, but may have missed it somewhere in the product description (looked back and still do not see that). I assumed it would be a sturdy solid plastic base and not an inflatable ring. That said, it seems to perform OK. Should it fail, I believe I could make my own stability base and use the resistance bands that came with it.

The exercise chart seems fairly comprehensive, I have only done a few of the exercises at this point. I am expecting the resistance straps to break at some point, but there isn't a solid reason for me to believe it, just that resistance straps have snapped on me in the past. The exercises require you to move the straps around, which the design makes pretty simple.

I normally use a kneeling rocker chair for my day to day office, which I love. I think this will...
