Review on YoYa Toys Pull, Stretch and Squeeze Stress Balls - 3 Pack - Elastic Construction Sensory Balls for Stress Relief, Anxiety, Autism and More by Duane Mann

So for how much my autistic son LOVES them I would give them 5 stars. But I had to give 3 stars because the plug in the ball is easily pulled out/moved apart and the filling starts to flow out. It's one of the few toys that helps his mental breakdowns, so I'm a little heartbroken that they broke so easily. Mouth. I tried re-gluing the connector but it quickly fell apart after squeezing again. It might work if you just squeeze it like a stress ball, but once you start stretching it will start destroying the connector. Maybe we have a bad batch?***UPDATE****My son has been playing with red for 3 days now and the cork is still tight and the ball is fine. Maybe the blue one was just broken. I hope it lasts =] I changed my rating from 3 stars to 4. So happy he's getting some benefit from this ball!
