So I just opened this and I squeezed it a couple times when suddenly the net ripped and made a little hole.It came with a zip tie on it so I couldnt rap it around so there is no hole but it is a bit hard to squeeze and is not that good.I have seen better for 50 cent one at a bowling alley.Fun & interesting toy. Unfortunately the ball somehow got a small pin size hole in it within a few hours of using it and gel started oozing out. The mesh bag also came undone at the top where it was being held together by a zip tie. I used another zip tie I had lying around to weave threw the holes of the mesh to hold it together again so the mesh won't get pulled out again, but then it got a hole.The ball I recieved was not what was describe or pictured. It wasn't a squishy mesh ball but a rubber ball that seems to be filled with some sort of gel, which I have to admit is more fun to play with than a mesh ball. I ordered two and both were different but filled with the same substance. It also came with two free basic foam balls which was nice even though I didnt need them. Overall this was a decent order even though it was not what I was expecting.This was the coolest toy that only lasted a few weeks. I wasn't exceptionally rough with it. I just squeezed it -- often.First the string bag pulled out of the black catch at the bottom. We were able to fix that with some specialized tools.Then the green goo started to pop out and the whole thing started to fall apart so it went in the trash.If they could figure out how to make it more durable this would be a great stress ball.This stress ball was a bag over a squissy ball with a zip tie holding the bag on! The bag kept slipping off so I replaced with another zip tie, but the zip ties don't stay. I then sewed the bag and then it was an enjoyable squeeze!It is fun to play with when you are stressed or just bored, but the mesh thing on the outside broke within the first day of having it. I have just been using it without the covering, but the covering is better. I would suggest looking around for a different one.This is a squishy balloon that is filled with gel and when squeezed, it causes the balloon to protrude through many little openings.I found playing with this ball to be oddly addictive. I enjoyed it at the time of purchase, and 6 months later, my toy still amuses me, although it's mesh cover has since fallen off.Its just a bright, fun, inexpensive little toy.I ordered this as a surprise for my six year old daughter because she had been wanting it and we couldn't find it locally in any stores. She was so excited when she opened the Amazon box and saw it. That excitement quickly changed when less than 10 minutes after opening it, and probably about 12 squeezes in, it broke and the inside color oozed out everywhere. She did not abuse it, just regular squeezes like you normally would with a stress ball. I had read reviews on how the quality was bad, but she really wanted it and I thought that maybe, just maybe, we wouldn't get a bad one. WRONG. What a waste of money. I know it was only $6, but still, it should have lasted longer than just a few minutes out of the package. I thought we would at least get a few days to play with it before it broke. So disappointing.
