Very lightweight and not good for fetching
These balls are very lightweight. They feel like styrofoam. I try to use my Chuckit Chucker to throw them but they don't go very far and the wind will drift them in another direction as they are so light weight. Then, when my dog's saliva covers the ball, the moisture creates a suction in the launcher and the ball won't exit the chucker at all no matter how much force I put into the launch attempt. I guess they might be good for chewers, but not for throwing, if your dog likes to fetch. They would be good for throwing in the house as they won't damage anything.

Shockingly impressed
I have a heeler and he destroys everything. I thought I was going to be unimpressed at first thinking these were going to be shredded everywhere, but I have yet to see him destroy these and we have had them for over a month. I definitely recommend for high energy aggressive chewers.

Cheap and easily destroyed!
I bought these balls because they are advertised as indestructible. Frankly, tennis balls last 5x longer! We breed Cane Corso, and these don’t last even a few minutes with them. Definitely not indestructible and definitely not for aggressive chewers. Very disappointing. The search continues….

Great balls
So far so good. Belgian/pyrenees mix that loves chewing and destroying toys. He’ll have a hard time destroying these. They are light but carry well once thrown outside. Being light they are good inside on very cold days compared to something like a lacrosse ball. Better than Chuck It brand.
