First Alert CO615 Carbon Monoxide Plug-In Alarm with Battery Backup and Digital Display

Install 2 AA batteries, plug it in, and you're done.

It leaves one plug still open on a standard wall outlet, and you can test it with your TV remote.

Haven't had trouble with false alarms except when the kids are playing with infrared remote controlled toys.

NYS law for all condos, co-ops and rentals require CO 2 alarms installed. This is the smartest protection as it has battery back up if there's a power outage. Most stores like Home Depot and Lowes only carry the less reliable and more expensive Kidde alarms. If you're in NY I suggest you purchase through Amazon and save time shopping and money.

Pro:
Its a CR Best Buy.
You can plug it into a power outlet without worrying about pre-wiring.
It has a battery back-up in case of power out.

Con:
The display on the unit is not the best but then it has an audible alarm.
Since most of the power outlets in homes are at the bottom of the room. Using it with the power outlet means the unit is always at the bottom of a wall.

Overall I have had no issues with the unit and I will recommend it for anyone to buy.

This product was easy to set up and arrived as promised. I bought it based on independent rating reviews, so I assume it work as described. I have not exposed it to CM in the home and hope it never will be.

Good instructions, easy to install, green light shows it's working but it's too bright. Recommend, based on magazine reviews and how it's been working for us.
