Terrific product
Color: A1-Red
I adopted a 2 year old cat - she’s not much for a lot of the toys I have purchased for her, until this one! At first she seemed very cautious with it - but still followed it around - once I slowed it down (a few different options) she loves to play with it! Great purchase very pleased with it

Fun & Fast moving toy for my cats!
Color: A1-Red
This is such a fun little toy to keep my cats entertained. They were definitely weary about it for the first few days, but started to get used to it and play with it after a bit. I wish there was an even slower option because the slow option is still pretty fast, but at least it gets them up and moving. They will even play with the tail part when it's not turned on. Like others have said, it does collect hair pretty easily, but it's very easy to clean off. I don't have any dogs, but I could see smaller dogs loving this as well!

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.
