They are nice and came with everything ready to install. I hope they never have to work, but they are there. Should I need them too?

The green LED blinks every 30 seconds. So if you have this anywhere in your house that you might be close to for extended periods of time, it'll drive you a little nuts.

Buying a pack of 4 was perfect for my mom's multi-level home. And compared to HomeDepot price, this is super economical. Installation was super easy!

Replaceable battery, easy install. Time will tell how effective this unit is. It’s handy to have both monoxide and smoke in the same detector, with a digital display on the front.

This works just as it should for smoke! I don’t have a way to test the co2, but that’s ok. I was thrilled to find such a lightweight unit that even included the batteries! Was quick to mount (hardware included) and has already tripped after one tuna searing session! Love it!

When I tested the alarm, it was loud which is great! I haven’t mounted it yet so I can’t comment on how easy it is to install, but it comes with everything you need and instructions. I love that it takes AA batteries! Good value!

Currently using this for the basement, kitchen, living room, and 2nd floor. Alarm is pretty loud. Full house coverage for $66 is inexpensive. Will update if anything happens.
