YIQUDUOYIQUDUO Plus Size Large Brain Squishy Squeeze Ball Giant Jumbo Big Brain Ball Stress Relief Toy, Fun Toy for Party Favors

Great size. Nice and squishy. Feels sturdy, but will have to wait and see how this holds up in my classroom.

Getting a lot of use in the classroom and it upholds well. So many of my students have asked where they can get it too.

Got it and it popped with just like two or three days of having it! Total waste of money! So disappointing.

It's about half the size of an adult brain, but it feels pretty good. Not sticky or slimy. Just soft like a giant marshmallow.

My (much younger) brother won a toy brain squishy. My whole family fell in love, so I tried to find another one like it. My fam was counting on it being as huge and fantastic as my brother's so we could find it again and again and buy some for nearly every member of our immediate family... Needless to say, I'm beyond dsappointed. I found the one in the pic, my little brother's, finally. It's $5. This one is half the size, much lower quality, and doesn't even meet their own, explicit size specifications. They say 5 inches... It is barely over 4, even the box is about 4 and half inches. It's half the size, over twice as expensive, and much, MUCH lower quality. Even without the comparison to the one we already have, even my brother's brain toy aside, it seems downright scammy. Look at the product pictures!! It looks as big as my brother's does. Look at the size specifications- it's even smaller than those. They OBVIOUSLY tried to make it look bigger and seem like a huge toy of great quality. Needless to say, I was completely shocked by the size. Also, for reference, the toy my brother won was ALSO SUPPOSED TO BE 5 INCHES. It's much bigger than 5 inches, and the quality is so much better. So which would you rather have? The ones that rounds down and is actually huge, or the one that rounds up to seem better than it is, even when the quality is lower and the price is higher???Totally a scam. Absolutely a scam. I am NOT happy.2 stars because it does "work" as intended, but is much lower quality than expected and it appears like it would fall apart after just a few uses. Meanwhile my brother's has been severely mistreated (oh so severely) for a week so far and hasn't even come close to breaking (he's a kid but mine I will absolutely treat better). But again, even still, his brain toy is so much better quality, and even better than advertised... For less than half the price of this scammy thing.

I love this Brain stress ball! I Have used stress balls for a few years, I have cerebellum ataxia & this Brain one is quite fitting for me. It's just perfect

My kiddos arrived with a small hole that we covered with tape because she couldn't bare sending it back. Since then it has been played with everyday and has no issues. Lots of fun and even quite large.

I have owned 4 of these in the past 5 months. Each one has exploded or leaked after a few days to about 2 months of occasional use. I own a business that is brain-based, so these are fun for my younger clients to play with during sessions--also a favorite of my fidget toys. However, I wish they lasted longer. I have been unable to get refunds because the price point is over $10 and Amazon requires me to send the item back to be refunded or replaced. The mess that happens when they break does not allow me to send it back, especially when it happens mid-session in the middle of a busy day of seeing multiple clients. Disappointing, but a big hit with my clients!
