My puppy loves it! It is not to big for him to pick up and toss around. It scared him the first time it squeaked. The only problem is my other dogs like it too, so I will have to order a cople more!

positive

Buying these is like playing Russian roulette. If you get a good one, like a friend of mine's, they are well worth the price. But the one I received had parts that did not lock together and the rotor wobbled. I returned it.

negative


Ex Input:
