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.

Not worth it
Very colorful and my poodle liked the ball. It didn’t last 1 week. Horrible quality and not worth the money. My dog destroyed ball as soon as I turned my back. Would return it if it was in a returnable condition
