Task: Sentiment Analysis
Input (English): Review: Takes more time to cut open the box than it does to plug in. Just plug it in, hold the test button, stick your fingers in your ears so you don't do deaf, and your all done. I've used First Alert products for many years, and they just work. They do wear out (5-7 years), but they will alert you when that time comes, usually with a chirping, like other detectors do.Simple, easy to use, no fuss peace of mind unit. Plug it in near air vents in bedrooms or just in open ares for non-living quarters and that's it! 
 Polarity: Negative
Output (English): False
