Input: Consider Input: this DeLonghi DFH550R heater is an extremely poor product and the customer service is non-existent,doesn't have a physical address or phone number and never gives their names...buyer beware...read their absolutely ridiculous return policy before buying...if you open any package they won't take it back...if you write a truthful negative feedback, they'll be after you like " ticks on a hound " !!!

Output: Negative


Input: Consider Input: Do not buy this toy. If you are given this toy as a gift, return it for store credit. This is a flimsly and poorly designed stack of platic and paper. The secret door doesn't work, the elevator doesn't slide and toys get stuck in there. The suggested 10" batman doesn't work with the zip line, bungee or even the elevator. The add says "Using new adhesive technology, you can set up the Batcave on just about any wall" so they want us to glue this thing on to a wall.Please don't buy this toy.

Output: Negative


Input: Consider Input: I actually didn't finish this book. It had some good pointers within it but I felt it was doing more story telling than teaching me how to calm down and deliver a speech without my breakfest or lunch wanting to errupt. Although it was somewhat interesting it wasn't doing what I needed it to and that was to teach me not to want to disappear before I got up in front of a group of people.


Output: Negative
