Feel safer now.
I just moved into a modular home and there was only one smoke detector there. I needed more than that so I found these with the carbon monoxide combined. The price was right and there was 3 of them too. I feel much better now and safer with 3 of them in my new place.

Received 3 smoke detectors with LCD display that can tell smoke or co, this is a lot better than the old detectors I've used, I love the design. Tested smoke is very sensitive, and it is easy to restore the original state. I installed three smoke detectors in the kitchen, hallway and bedroom, and the triple detection should ensure the safety of gas use throughout the house.
