Excellent product and easy to install

Don't know why a product like this wasn't available the first time I bought CO detectors years ago, but it makes sense that they could be plugged in to an existing electrical outlet and have a back-up battery in case the power goes out. The only thing that I think would improve such a product is if it had a ten-year sealed lithium back-up battery installed in it. But, since they are plugged in so low to the floor, replacing the batteries is not much of an inconvenience. This is a definite improvement over the battery-only kind of unit. I think this new unit provides increased peace of mind.

The importance of carbon monoxide alarms

We all know how important smoke detectors are in our homes. But carbon monoxide alarms are just as important. One thing that makes carbon monoxide poisoning so dangerous is that it is a deadly odorless, colorless gas. This alarm was basically just "plug and play". You just plug it in and it works, testing for carbon monoxide immediately. It has a small green light that lets you know that it is working and that no carbon dioxide has been detected.

I ordered a bolt quantity, for my renters, and Walmart was the only place that could accommodate the amount that I needed and get it shipped in a timely fashion with a decent price!
