These perfect smoke detectors are great. No screws needed and batteries are included. Simply place the battery, remove the sticker off the back of the magnet place the sticker on a clean surface where you want your detector and thats it place the detector to the magnet and test it out by pushing the test button on the top of the detector. This magnet to the detector is very strong as well as the sticker adhesive. I’ve placed the sticker on painted ceiling, untreated wood in my basement and have had no issues since purchased. Definitely recommend this pack for the safety of your home.

These seem like good smoke detectors. I don’t know what we’re talking about an internal battery or a battery back up. Mine only has a 9 V battery. It does not work unless the 9 V battery is connected. Hopefully they last 10 years or close to it because I have very high vaulted ceilings and it’s a big pain putting them up.

I would definitely recommend you buy these smoke detectors to keep your family safe and the price is right

I got tired of expensive First Alert and Kidde smoke detectors that are nothing but junk, continually sounding an alarm over nothing and winding up in the trash. These detectors are superior and cost much less. No false alarms and actually work when tested with smoke. A handy adhesive pad is included making installation very easy. The adhesive is aggressive so you have one chance to position it. Battery included.

Sticks so easily and works great. I hate putting holes in my walls so these were perfect to stick on and leave. I have weird textured paint that looks and feels kind of oily and it doesn’t affect the sticky whatsoever. Will buy again.
