Fun but not for rough play.
Color: Orange
The ball contented our “golden” Jaxson for about 15 minutes. He then thought it was a regular ball and it’s just a little delicate for a big dog. I just wrote it off as a loss. Great idea but should be more durable.

Long lasting charge!
Color: Orange
My 50 pound goldendoodle absolutely loves this ball. It keeps a charge for a long time. It turns off When it’s not being used and we play with it every day.!

Great to keep your dog entertained
Color: Blue
Great toy my 13 month old cane corso absolutely loved it and it kept her entertained forever except she has an extremely strong bite so she was figuring out a way to split it apart so I had to take it away -it’s extremely strong, but not strong enough for the bite of a cane corso but any other dog would love it. I just wish my dog didn’t have such a strong bite and would be able to keep enjoying it since it is a little expensive the only problem with it is that I thought the remote shuts it off, but then her bites were making it come back on, so I don’t know if it was my dog or the toy just doesn’t stay off until you turn it on.

Stopped working within 3 days
Color: Blue
Worked for 3 plays. My 11 week old puppy loved this item. Unfortunately, it only lasted 3 tries before the motor stopped working. $30 for a total of 30 minutes over 3 days is robbery! I'd look at another vendor for the same type of item. We charged it after each attempt but now the motor won't turn on.
