Review title is Hard plastic shell with soft cover, not impressed [SEP] Nope! Gave to 2 different dogs and neither liked it. First, it’s not a ball. It’s a hard plastic round shell that has a battery placement inside of it. On the outside of this is a very flimsy on off switch that works like a ball point pen. It turns off when the ball rolls over it. There are extra covers for the ball which is nice. It rolls pretty well for a few minutes, but then just stops. The 2 dogs I gave it to did not care for it. Maybe it’s better for a cat. I don’t recommend this, especially for super chewers.
