Example Input: 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.
Example Output: Good Review

Example Input: Easy to set up and easy to use. Well worth the money for an added tool on your tool box.
Example Output: Good Review

Example Input: Like the other reviewer, this adapter started out doing ok, but with no warning, it will now not recognize my laptop and I have to plug in another one or find a replacement at a local store where I'll be guaranteed to get a quality device.
Example Output:
Bad review
