The following day, it had visibly lost air

Good while it lasted, unfortunately the ball just randomly lost air one night and is unusable.

Yes, my son likes to superman on this also, it's a good active play break prop for him while we have this poor air quality outside

Loses air have to reinflate every couple of weeks it does help a lot with pain but have you have to put a lot of air if you only use foot pump that is included

The actual problem is that the ball keeps deflating, I guess it has a puncture somewhere or is losing the air thru the inflating hole

(I don’t know if there’s a faster way to inflate the ball without getting some noisy air compressor.)

I definitely think it would lose air if someone sat on it, or even leaned against it on the wall.

after I got it it needed some more air but the pump was completely leaky at the base and leaked more air than I could pump so now I have a deflated ball with no way to refill the air.

We have had the ball for about 4 months and it keeps losing air.

In fact, I'm pleasantly surprised to find that they seem not to have lost *any* air in the months since we snagged them

I had planned to leave the exercise ball inside the model, but it started to lose air the second day of construction, and that made the whole concoction start to collapse.

Now two months in and looses air.

It was great except for the fact that we had to pump it up again every day as it would lose too much air.

It was great up until it started loosing air for no reason

I have had this ball since June and it’s already unusable because it looses air so quickly

but it looses air and has to be pumped up 3 times a week

First one was loosing air

They were simple to inflate and they hold air very well (haven't had to re-pump in the month since we got the first one).A note on

n’t know why it leaks air

4 nights ago & no air lost

I've had cheap ones that never lost air

Have to refresh air every couple of weeks!

there has got to be a better way to pump up the ball, it takes at least 30 minutes to get enough air in the ball, other than that, it is great and very strong

but the next day it had lost air again.

Did loose some air the first week or so but after refilling was fine

Trideer exercise ball is leaking air trying to get it replaced, please advise....

It has been loosing air since the first time we inflated it.

In fact, I'm pleasantly surprised to find that they seem not to have lost *any* air in the months since we snagged them

and it has not lost air nor given me the impression that it's going to burst.

This takes a full 20-30 minutes to blow up using provided piece of garbage air pump.

Hasn't lost any air since I pumped it up

The air pump arrived defective which is preventing me from getting accurate air into the ball

I have had my ball for a couple of weeks now and noticed that after a day or two it loses air and i must repump it up.

It keeps its air very well

Once I got enough air plugged it, my son found a small hole.

Foot pump does not blow much air

However, after a month and a half, it seems like the air keeps leaking out

Update 12/26- after having it for a month or so, it’s starting to loose air as I use it

However, after a month and a half, it seems like the air keeps leaking out

Took 20 minutes of continuous pumping with pump provided, then the air leaked out

is good but will lose air when trying to pout the pin in the ball.

Product does not hold air seems to leak at the fill site and main seam

Keeps losing air instead of being firm.

So disappointed as I don’t have a way to inflate it.

Disappointing as I was really looking forward to using this as my work-from-home office chair.
