Wouldn't buy again
Flavor Name: Boy, Size: 8 Count (Pack of 1)
They were all individually wrapped which was annoying to take them out the wrapper without them falling apart

Dog hasn’t destroyed the ball yet!
The ball that comes with this is amazing. I have a 1 yr pitty that destroys everything! But this ball she has not been able to rip apart. I bought extra balls I was so impressed. She loves it too, takes it to bed with her.lol

Cheaply made , waste of money
Cheap !! Lousy product did not fling at all. Lost the ball almost immediately since it went back instead of front. Do not recommend

So-so
Do not like this as much as previous one that broke after years. This one is cheap and sometimes the ball doesn't flip out well and doesn't pick up balls on the ground as easy but it does the job.
