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: Not easy to use and I found the results not very accurate! You need a good eye for such details when you are taking your blood pressure. Also in order to get accurate readings one needs to watch one's pulse. If you take this type of device with an expensive equipment than it is wise that you go there first if you're new at using it. A great gadget!This unit was probably a bit older or something, which is why it had problems.
Example Output:
Bad review
