This ball has been a great way to keep my dog entertained, especially when I can’t play nonstop. The movement really grabs their attention, and the 3 play modes are a nice touch depending on how energetic your dog is feeling. It works well both indoors and outside, and my dog loves chasing it around. It's not noisy at all and has thicker material so it cannot be easily chewed or ripped. The E-TPU material feels durable and has held up well so far, even with pretty rough play. It’s easy to use, simple to switch modes, and keeps my dog busy for a good amount of time without getting bored. Definitely a fun and engaging toy for medium to large dogs, especially if they need extra stimulation. Would recommend for supervised play!

Keeps the dog occupied

The ball seems to work fine. My only complaint is that it’s a little loud.
