Good quality and definitely worth it for energetic dogs.
Color: Orange
The automatic moving and rolling action really grabs my dog’s attention, and the rope adds extra fun for chasing and playing. It helps reduce boredom and keeps my dog mentally stimulated, especially when indoors. The motion activation works well, and it’s a fun and engaging toy overall.

Best Dog (Puppy) Toy I've Found
Color: Orange
This is a fun toy for me as well as my puppies! When it arrived I opened it right away. I was anxious to get my Pup's playing with something that wouldn't require me to play with them. I put it down and it was charged and ready to go. I had no idea what to expect. All three of my Pups were interested in it. (Which is unusual because two of them are Shih Tzu's and don't pay a lot of attention to most toys.) It's safe and really cute to watch. My youngest pup had been playing all day and was tired when I finally took a photo. I can't tell if the video uploaded correctly but if it did you can see how much fun it was. It is very durable and can actually turn itself over and go across the floor. It charges fast and will last a day and a half or two depending how much it's been used. It does go to sleep if no one is playing with it. They furnish you with an extra top and a fresh "rope." I really appreciate how much customer service is done with this item. I will watch for more of their items to purchase.

Buy 2 at a time for a fun experience
Color: Orange, Color: Orange
What’s better than 1 toy? Answer: 2 toys! I love using two at a time. More stimulation and fun! We use these to get all the energy out before nap time. They keep him occupied and running in two different directions. The rope part of the toy is the perfect size for him to grab onto. It came with a replacement for a wheel and rope and haven’t had to replace it yet. Toy has held up with daily play and still works perfectly.

How many dog toys have you bought that just laid on the floor unused?
Color: Orange
New husky has more energy than an entire pre-school - even being walked more than three miles a day wasn’t sufficient to drain her excess energy.
I threw the dice on this - and it’s AWESOME. Comes with an extra rope and an extra side piece. Rechargeable with a USB-C cable. When you turn it on, the blue LEDs flash, the entire device buzzes, bounces, and races back and forth across the floor. After a couple of days of uncertainty, my new husky LOVES this. She chases it around, grabs it by the attached rope and carries it from room to room.
After a short bit of activity, the toy goes into ‘sleep’ mode, until either the dog touches it again or a timer has elapsed, and then it fires up and starts buzzing and racing around the floor again.
From a full charge, the toy will keep your dog entertained all day. Bright orange color makes it much easier to find when it’s rolled behind the toilet (as it did this afternoon). Sturdy. Highly resistant to chew damage. If this one wears out or breaks, I’ll absolutely get another one.

Puppy interactive toy
Color: Orange, Color: Orange
It’s a great toy as it keeps my 5 month old puppy very entertained! It is pretty hardy and made of good material as she tries to throw it around and chew it. She does swing it around and the hard part will hit her. She doesn’t seem bothered by it tho lol good size and minimum noise
When I first introduced her to it she was a little scared but now she gets excited to play with it once it finishes charging.
