That it’s usable for more than one day
Color: A3-Pink, Color: A3-Pink
The toy itself is great and my puppy enjoyed it. My problem is that it didn’t come with a charging cord and none of mine fit. It never changed colors. Maybe if I had a charger cord it would be worth it, but right now it’s useless!!

Fun for Fido but flimsy
Color: A2-Blue
My 15 yearold mini Schnauzer, Sam, played with this for less than 1 hour and tore the rubber sleeve off it. I will say the toy itself is a genius idea. Sam was absolutely ensconced. I wish it were made sturdier.

It does exactly what they say it does! Worth the money
Color: A1-Red
It arrived quickly. It’s a fun toy! It’s the right size for cats. Definitely worth the money. It is exactly as described. So far, the quality seems very good and it seems durable. The instructions are on the side of the box, which makes learning how to operate it easy. I love it that it’s red, because my kitty seems to be attracted to red. My kitty is very interested in it, yet isn’t quite sure what to think of it. I love that it changes directions on its own so that it doesn’t get stuck or lost under furniture, which is typical for a ball that cats play with. It seems to only go two, three or four feet in one direction and then it changes directions, which is both good and bad. I just wish it would go farther in one direction before changing directions so that my kitty could chase it farther, as we have plenty of space in our house for her to run. But that certainly could be a plus for other cats, enjoying not knowing where the ball is going to go next and really keep them on their toes.

Cat loves this
Color: A1-Red
This toy is great for keeping pets entertained. The ball moves quickly and the tail makes it even more fun for cats to chase. It’s rechargeable and easy to use, and my pet stayed interested much longer than with regular toys.

Great quality and flavor
Color: 3PC-Bacon-Brown, Pattern Name: Tough Dog Toys
I have two dogs that can chew through everything within a day. Not these, going on four days now, there are signs of wear and tear but still intact. The dogs love the flavor.
