Example Input: My dog loves these so I buy them in bulk for her. But it is a rip-off to pay $6.45 at the pet store and $4.88 here. Not cool because it's cheaper on Amazon. Buy elsewhere if you can't find these... then you will have paid too much! It is almost as silly paying Amazon more than double price...when I can get 6 or 8 of her faves from the store. So disappointed. Will not order again. And don't forget...
Example Output: Bad review

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 love having the option of either setting this item up on my dashboard or hanging it from a window. The suction is strong enough to hold for even days without adjustment. Very easy and convenient. My first set also came with an extra mounting pad so I'm happy that we won't have to buy one as often. Definitely recommended over many others I've tried!
Example Output:
Good Review
