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.

Great toy
Color: Blue
Great toy, too bad my Shih Tzu is afraid of it. I love the way the movement is subtle and random.

I wouldn’t recommend this for strong chewers.
Color: Orange, Color: Orange
Is it fun? Sure. Was it easy to charge and set up? Yep. That being said, this toy kind of fell flat for me. It really didn’t do any big movements once charged that I expected it to, so that was a bummer. I initially got it for my dog, but my cats were more interested in this than my dog was. The battery does seem to last a long time and the motor is pretty quiet. I WOULD NOT recommend this toy for strong chewers as the material for this is a foam rubber and I don’t think it’s durable enough for strong chewers. While the material makes this ball extremely lightweight for more movement, a strong chewer would have this disintegrated in five minutes flat. My Dog is a super strong chewer. I don’t think I would feel comfortable leaving him unattended with this because I know he would destroy it.
