Input: Consider Input: I bought this first alert CO alarm for my home in Wisconsin.When I started to read the instructions I found that this product is not UL list! How can a safety item like this not be UL listed.I did some research and found out first alert changed testing labs to save a few bucks and do not use the most well known UL. What's up with that...So I returned this CO and purchased the Kidde KN-COB-DP-H Plug-In Carbon Monoxide Alarm. The Kidde unit cost less too, so I saved a few dollars! Always pays to READ THE FINE PRINT.

Output: Negative


Input: Consider Input: Very simplistic writing style- he said, she said, then he said, then she said. This reads like a first attempt, not like a book written by a seasoned author of over 30 books.

Output: Negative


Input: Consider Input: When it started leaking I couldn't find the leaks. First the top started leaking, later the bottom so now I have totally given up on it.It was comfortable before it started leaking.


Output: Negative
