question:
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.
answer:
Negative


question:
I wish I could give this more then 5 stars. This concert tour was Tina's best concert. I almost did not buy this because I own this on video. When I recevied it, to my surprise, the DVD has four extra songs on it then the video. The songs are "Wildest Dreams" "Let's Stay Together" "Something Beautiful Remains" and "Better Be Good To Me" If anyone caught Tina on this tour, here is your chance to own the "complete" concert for ever!
answer:
Positive


question:
And these masters are Michael Bay and his computers!!!And we have no one but ourselves to blame!!!This movie is like a 2.5 hours car crash. When you think it can't get any worse - it does.It would deserve 2 stars if it didn't have any human actors. But Michael Bay is actually controlled by his computers, and they made him put these humans in this movie to make us suffer even more!!!This is all I have to say. Transformers IV is coming soon to the theaters near you. Preorder your tickets now!!!

Negative
