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.

Ex Output:
Negative

Ex Input:
I thought this book was long, drawn out, and boring. It was too descriptive. To me, the writing style is a lot like Jane Eyre. I don't particularly like that type of book.Plus, it was way too sad and unrealistic. I don't think THAT many bad things could happen to one person.

Ex Output:
Negative

This is just abysmal... Taking what was THE definitive horror trilogy for the 90s and changing the artwork because tightwad parents disapproved. Don't let your kids read the books if you don't like them, but ruining it for EVERY kid born after 2000? What a sign of the times... Family Guy/American Dad in the Simpsons spot, Twilight saga in the X-Files spot, Hunger Games sweeping Battle Royale under the rug, and now this...
