Not a durable toy.
This only lasted a few minutes before it was destroyed by our dog. Not made well for chewing.

not very sturdy for puppy chewer
The toy was large and it seemed to be made of good material, I was very excited to get this toy for my puppy, but the toy did not even last 24 hours. I was very disappointed. If you buy this product watch your puppy/ dog very carefully so they will not swallow any of the plastic or stuffing

Not good for aggressive chewers
My pup really likes the noises but it took him less than a day to destroy it. (He’s only 8 months old old)

For me this was a waste of money.
I doesn't bite well to my skimmer opening eventually the current will spin it out of angle. I would never buy another one. Maybe its because my opening it tile so it can't bite it hard enough when expanded.
