The product is great no issues. It’s very durable. All of this brands products are strong and durable. The only reason I gave it a four star is I think my dogs prefer more the blue round balls. So that being said, I won’t buy these anymore, but they love the blue ones whether they’re the recycled or not. Great company!

As you can see from the photo, my pup absolutely loves it! It’s the perfect size for him and for reference he’s 25 pounds. It’s got a nice weight to it, but it’s soft enough to be able to throw and not worry about damaging the walls. We just started playing with it today, but it seems very durable.
