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.

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.
