Durability
Color: Blue, Color: Blue
won’t give this product 1 star because my dog still had a good time with it for a few hours. After opening and preparing it, I gave it to my dog and it definitely caught his interest. However, when he chewed on it, plastic pieces started breaking off and he began swallowing them. This product is definitely not suitable for aggressive chewers.

Winner !!!
Color: Orange
This amazed us. For perspective, we're talking about a three year old white german shepherd who if he's in the mood, has and can kill a toy within minutes or oddly enough be gentle with furry balls and carry them around as if they are his babies. He's an odd duck. Anyway, since he was a pup, and to this day, he'll play and entertain himself, he'll grab a ball, throw it up in the air, then pounce on it as if it's from outer space. It's really quite cute and funny. Because of those two things I was looking for something interactive that would entertain him and confuse him....let's be honest, watching a confused dog is one of life's great pleasures. I tried two other interactive balls and they were crushed immediately. After reading a lot of reviews, people with german shepherds said this ball actually had a life span. I thought the third time could be the charm and ordered one. Well, I think it actually may be from outer space because he's obsessed with it and hasn't taken a bite out of it. He hasn't once chewed it or even teared little pieces off. The three settings are great. Sometimes he likes one better than another, then forgets about the others. I'll change it up to one he hasn't seen in a while and the whole game starts over again. He'll throw it up in the air as he does with his others, watch it and try to figure out which way it's going to go. And yes, he will pounce on it if he times it right. The size is perfect, it's heavier than your average ball but, that's what make it sturdy. I have to sneak it away when he isn't paying attention to charge it, otherwise he'll sit, stare and cry if he knows it's on the counter charging. It's a lot of fun for all of us. I'm so happy I bought it...... I say give this ball a chance even if you have a beast with killer instincts. I'm buying another for a friends 2 year old golden retriever granddog. Thank you Cheerble.
