Well-designed and quiet, but didn’t keep my dog interested
Color: Blue
My dog was interested in this at first, but she would lose interest after a few minutes and move on. I do like that it’s quieter than the hard plastic ball toys, and the charge lasts well. The internal charging port that twists closed is also a nice design feature. That said, it will occasionally turn on by itself, which can be a little surprising. Overall, it has some nice features, but it just didn’t keep my dog engaged.

Good - for a few hours
Color: Blue, Color: Blue
Concept is fantastic. Dog loved it. Problem is that she figured out how to open it within two hours of play. The robot core, alas, did not survive. In the photo, you see a tooth went cleanly into the button and that was the end of the toy.

The most engaging interactive toy for my Border Collie
Color: Orange, Color: Orange
My Border Collie is not a big ball player. He prefers tug type games and actually gives me a look like, “Are you stupid? I’m not going to keep bringing that to you if all you’re going to do is throw it away again!” after about the third time I throw a ball for him to fetch. However, I can only play tug so often and I need him to be entertained and engaged as much as possible. I got him a smaller, non-padded ball like this hoping he would like the interactive aspect of it. He did- he actually loved it! But it was loud, hard on his teeth, would come apart periodically, and he kept hitting the off button when playing with it. It drove me crazy. This one is so much better overall! The soft outer shell is not only easier on his teeth, but it is super resilient to biting and chewing. He actually likes to carry this thing around in his mouth while it’s bouncing and vibrating. The three modes give great flexibility for different kinds of play. His favorite is the most active mode: the ball reacts to touch and practically bounces itself across the floor when he touches it with his paw or mouth. I will point out that in one of the modes, I thought the battery wasn’t charged or there was a motor issue because it’s very subdued movement; however, it’s just set up as a low-key option. Be sure to check out each mode to see which works best for your dog at different times. I can’t say enough about this ball- I have been so pleasantly surprised by how much he loves it. The rechargeable feature is super convenient, it’s big enough to not get stuck under the couch, and it automatically shuts off based on whichever mode it’s set on. As the owner of a busy, super-smart dog who needs to be engaged in mental and physical activity, I think this all is worth every penny. In fact, I’m buying one for a friend who has a Border Collie pup with lots of energy to burn! I highly recommend this toy- it’s the most engaging toy I’ve found that Finn will play with on his own.

Not as Smart or Interactive as You Think it Will Be
Color: Blue
This is an honest review from a schnauzer owner who has has wanted this cheerble ball for their dog for more than one year. I finally bougI finally bought this toy and both me and my dog are disappointed. The settings are...i would say dog friendly as I'd assumed a dog ball would be. What I mean by that is, for example: the calm play setting is muuch too calm. Super light puffs of energy, like a battery is dying. And the playful setting is scary, alarmingly so. The intervals in between are too long. The ball does not bounce. So they just have settings all wrong. The size is good for a large dog only. Do not buy if you have a small to medium dog. I even think the material is okay. I've only had it for a few days so I can't even speak to how the material holds up. Really hoping to love this ball for my dog. It was not the distraction I was hoping it would be so I could work from home while my dog had fun. I'm hoping this can help someone else who's been pining over it. Essentially, it's a $35-$50 well made weighted ball that moves occasionally.

Works Great! Very bright
My dog and I really love this ball. Bought this so we can play in the field behind our house at night. Tried other balls, like the glowing ones, but they're not bright enough. Other battery powered balls don't stay on long enough and I got tired of looking for them in the dark. This one stays on, depending on the switch setting, either 5 minutes, or indefinitely until it's shut off or until the battery dies. The battery, according to the instructions, should last 10 hours before needing recharging. I've charged it once when it was received, haven't had to re-charge it yet, played with it about 7 nights now 20 min each time and it's still going. Others have said it's not very durable, but I've found it to be durable enough to play catch with our border collie, haven't had any issues. but I don't let him chomp on it all he wants, just throw it and he brings it back. I suppose if your dog is an aggressive chewer and you let him just sit there and go to town on it, it won't last very long, just like any other ball. We use this ball only at night when needed, and use cheaper balls at other times to increase its life span.
