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: As well as a trilogy that is as far-reaching as it is set in a far-distant time with characters and galactic backdrop unrivaled by any other book. Definitely one of the great science-fiction classics just like "Stranger in a Strange Land", "Childhood's End", along with modern-day cyberpunk like "Neuromancer", "Count Zero", "Prey", "Cryptonomicon", "Snow Crash", "Darkeye: Cyber-Hunter", etc.
Output: Positive
