Easy to install, cost effective. and reliable

This detector is considerably less expensive than traditional detectors because it doesn't utilize a 3-pin connection to a 120V power source. This allows flexibility in placing detectors on the ceiling. when replacing an existing detector, simply tuck the 3-pin into the ceiling and place this detector over the existing hole. A drill is needed to install the screws.

X-Sense Fire Alarm 2 Pack With 10 Year Batteries!

X-Sense Smoke Alarm with 10-year sealed batteries and LED indicators in the 2 pack have lithium-ion batteries which I found strange since they have been known to cause fires, but I believe the company should know what they are doing. 10-year sealed batteries are code where I live. The instructions and print are extremely small even with a magnifying glass. Fairly easy to put on the wall 4" to 12" down from the ceiling, I cannot climb and do not want one on the ceiling. Older people are a fall risk. The 2 pack was a better price, and I have no experience with this brand. It is loud and we have others that will go off as well making it louder! Praying these are the right brand!
