This product cost $50 so it is a little spendy. i had carbon monoxide twice in my apartment. i bought this one to replace those. The fire dept came both times with the other two incidents, but the fire dept said they could not detect the gas. Hopefully, one works well. It was easy to install.

Expensive!
I went back and looked for a box of smoke detectors, I needed one for each room, 5 in total. This one was pretty pricey so I continued my quest. Walmart is a great place to find stuff like this, they really do have some of the best values around.

I feel safer.
It already works. I left a pot on the stove and it set the alarm off. I feel safer.
