Example Input: This heater works really well. You set temp's to desired amount of temperature,its a lot like a big space heater. It will blow cold air into room very quickly.
Example Output: Good Review

Example Input: I am not a huge fan of the taste of this coffee. The pods tend to get stuck in my machine, leaving me with coffee and grounds everywhere. Also, some days it still doesn't work - makes coffee but no water. It is nice and hot which can be good, however after having used it for two weeks I'm afraid its just another piece in our garbage. Very disappointed :( will use regular K-cups again :)
Example Output: Bad review

Example Input: What it is, is a book of ideas I read at the last minute. But if you are familiar with these ideas, they will not be new, as Mr Wilson has been repeating them for yearsThis book in no way stands on its own, and lacks any depth to it. It might have one or two good points but overall does not, in my opinion, add up when taken out after you've gone through every page or 2 in it.
Example Output:
Bad review
