PROBLEM: This machine is really good, but not without some problems. While the noise it makes does a lot to mask other noises, our cats definitely do enjoy this thing. It also helps keep them calm, which in turn, brings us much peace of mind. However, sometimes you need your hands free for something else -- like getting the cat out from between the mattresses.

SOLUTION: Good Review

PROBLEM: This was the worst album i have heard in a while and my friends who said they love jay-z must not be true fans because this is garbage if you want to get an idea of what jay has been through go to his website then download it from there its free dont waste your money people cause hes wack now thats how he is!! Im done with him keep tryin..

SOLUTION: Bad review

PROBLEM: It was easy to install and I loved the idea how all three of them worked. That is, my cats played with it. But this toy lasted 1 day before one of the ends stopped working. One more thing we have found that is not made in the US anymore. And even the name is an import. Go for a Kong toy! 
 Rating: 3.0 
 Our cat loves tennis balls so she likes it but unfortunately they don't last long.
