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.

This is Willow The Dog’s favorite toy!
There is not much that needs to be said about this, frankly, amazing dog toy find.
After about 6 months, Willow absolutely loves this seemingly indestructible, soft stick toy. She was born a stick dog and has always enjoyed fetch with tree limbs, balls, frisbees…And like most dogs, loves tug-o-war and chewing.
I thought I was buying a <$4 toy stick that I expected my girl would destroy fairly readily. What I actually received was something that didn’t really match the description because it had MORE features and uses than I expected.
Anyway, the short of it is in the video.
What she loves:
Fetching:
I don’t know how dogs see colors, but I can confirm that my dog finds this toy highly visible day and night. This claim is based on my observations of how she retrieves this toy compared to real sticks, yellow and blue tennis balls, a large real bone, and rope toys both night and day, as I work late, so much of my one on one time with our pup happens around midnight to 1am with no outdoor lighting so we don’t disturb sleeping neighbors as much. Additionally, I find this toy highly visible in all conditions, which would make finding it in the grass after Willow is worn out and goes inside easier, except that she loves the toy so much that she always brings it in with her.
Tug-o-war:
Being a soft, ultra-durable material, this toy eagerly pulls double duty as a tugging toy. Dog teeth sink into the orange material by compressing it. They do not puncture the orange part, or at least not that I’ve noticed while casually examining it, making this toy last indefinitely, so far as I can tell. The size of the stick is roughly an inch in diameter and maybe ≈14-16” long, so it is, I think, a perfect size for my medium sized Australian Shepherd’s mouth. She can grip it solidly in her back teeth, side teeth, front teeth, and even if she has only two or three teeth in just a corner, she can always get a good, comfortable grip. No sharp, jagged edges of frayed plastic to abrade or irritate the inside of Willow’s mouth, gums, or cheeks and no orange material breaks off and gets swallowed. The blue material is somewhat more rigid, like a plastic, BUT is still fairly soft and while it does show some bite marks, it is still quite durable and is, I will estimate, at least 95% intact after about 6 months of average three or four 15-20 minute sessions each week. Additionally, the size happens to be perfect for my large hands, but also feels like it is appropriately sized to be easily manageable by most people. This toy is VERY flexible and gives both Willow and I excellent maneuverability and pulling left to right and up and down and back and forth and to and fro as violently and aggressively as we can manage with out the rigidity of other objects shifting uncomfortably in her mouth or my hand. The stick is long enough to accommodate both my large hand and her mouth, even both of my hands on either end with her biting in the middle.
Chewing:
This not Willow’s favorite chew toy, but to be fair, it isn’t really marketed as a chew toy, so I feel the degree to which it fulfills that function is “good”, which I consider to just be an added bonus feature AND an extremely good value for the money. Anyway, she brings it inside when we are done playing outside and chews on it occasionally, apparently when she wants a break from her seemingly endless and evidently boring selection of toys, enrichment gadgets, kids, neighboring dogs, and family cats.
Summary:
At $4, even if your dog picks it up and walks on her or his hind legs to dispose of it immediately upon presenting it to them, it will be worth it just to see that, but if your dog loves it as much as mine, you might, like me, be so pleased with it's contribution to your dog’s life, you may start doubting your sanity when the strangest thought creeps into your head as you actually consider “refunding the seller” by sending them an additional $3.94 because they absolutely deserve to be paid more for this wonderful toy.
Enjoy!

Perfect Toy
My dog loves this ! It is very sturdy, very strong, but flexible. It feels soft, but seems chew proof, even for my 100 pound Cane Corso. The stick shape is more practical than a ball; it doesn't roll off or get lost under furniture.

Good toy, strong yet soft!
This was one of my best toy purchases for our GSD! He’s a rough playing dog with a hard mouth! Toy destroyer! This he loves to fetch, tug, carry, and chew on. I never really expected it to last when I got it. Surprise! Almost two months of rigorous daily play and it’s still almost like new!
