Great quality ball
Color: Green, Size: Medium (2-1/2 in (Pack of 2))
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!

Pups Love
Color: Green, Size: Medium (2-1/2 in, (Pack of 1)), Color: Green, Size: Medium (2-1/2 in, (Pack of 1))
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.

Fun for the first day, but just get the round balls.
Color: Green, Size: Medium (2-1/2 in (Pack of 2))
These balls do work, but they bouncy pretty
much like a regular chuck it ball. They do NOT fit in the chuck it handheld ball launcher, which makes them a pain to throw. The green color also makes them somewhat challenging to find when the grass is long.
That said, they do work as intended, and the dogs like them the same as all the other chuck it balls we own. As the person who had to throw them, my advice would be to just get the round balls that fit in the ball launcher.
Durability: 9/10 they hood together better than the traditional balls without the hole (that crack down the seam over time). These have yet to crack despite the same wear and tear.
Pros: durable, dogs like them, they do sink in water
Cons: green color, hard to fit in handheld ball launcher

Winner!
Color: Green, Size: Medium (2-1/2 in (Pack of 2))
I recently got the BOUNCY DOG BALL TOY for my fur baby, and I'm thrilled to say that it's a total winner! The best feature of this interactive dog toy is its erratic bounce, which keeps my pup on their toes and makes every playtime session full of surprises.
The squared corners of the ball cause it to bounce every which way when thrown, making it an exciting challenge for my dog to catch. And because it's compatible with the Chuckit! Ball Launchers, we can play fetch for hours on end without ever getting bored.
One thing I love about this fetch toy is its durability. It's made of tough rubber that can withstand even the most aggressive chewers, and it's super easy to clean after a long day of play. Plus, with two balls included, we always have a backup when one inevitably gets lost.
