    Paint was exactly as advertised. Communication was excellent. Seller quickly shipped item. Paint had a piece of tape across the top to prevent the lid from somehow coming off. The can was also in a ziploc bag. Very well packaged! Item arrived faster than I expected. Thank you!

    Easy to use, A++

    It's a good product and worth the price, easy to read. And the battery backup was great just in case there is a power failure.

    Easy to install carbon monoxide detector.

    Plugs right into a wall outlet and works. It tested OK with batteries installed. Since plugging it into the wall outlet is has not gone off, which is what I want it to do unless there is a carbon monoxide leak in the house. I wanted a detector that runs off of 120 vac and has battery backup, which this one has.

    A must have item.

    Very accurate, works great. Replacing the same type due to the age and expiration date.

    Good CO detector

    Well rated in Consumers Report and seems to work fine. Has a digital readout, battery backup, and end of life warning.

    Good Detector

    I wanted a carbon monoxide detector with a read out that would tell you what the level would be if it goes off. Hopefully it never will go off. Nice look and great price.
