Review: Sensitive regular cooking and a vape triggers them - They work. I hate them. Can go off during normal cooking. Triggered by vape. I'm sure if you are an in door smoker it will go off for those too. They are fine as it's only once in a while. 5 star because they do work. Better to be over sensitive than not sensitive enough I guess.
Review: Smoke Detector - This is our favorite smoke detector. They are reliable and have great reviews. They work when they need to and we trust them. This is our second one. Our first one lasted 7 years and we were happy with it, so we purchased it again. When this product needs to be replaced it will start beeping very loudly and not stop until it is taken down and disconnected. It was actually cheaper to purchase here on desertcart rather than buying it in the store. Installation is very easy, just remove the packaging and hang it up.

### ⭐⭐⭐⭐⭐ Smoke Detector

### ⭐ DOESN'T FIT EXISTING MOUNTING RECEPTACLES
*by J***E on April 21, 2025*

Just installed it, so can't comment as to whether it functions as intended, but whoever designed the mounting bracket was either incompetent or a sociopath. Bought this 20SD10 model to replace a Kidde i12060A that lasted 10 months (not years) before it started chirping randomly in the middle of the night, even with a fresh battery. The mounting plate for the prior model does not work with this unit. Perhaps there is a good reason for it. HOWEVER, the holes for the mounting plate are at a different distance from each other than with the prior plate, AND a different distance than the standard ceiling receptacle. Moreover plates like this typically have a larger hole that fits over the head of a bolt that has been slightly unscrewed and can then be twisted so that the bolt can be tightened. This eases installation. This plate requires both bolts to be entirely unscrewed (not a trivial task with a ten-foot ceiling while on a ladder) and then screwed in while the plate is obscuring the bolt holes. The ceiling receptacle has pre-drilled (actually molded) holes that are 2 and 3/4 inches apart and 3 and 1/4 inches apart, as did the prior 2 Kidde detectors. I was able to mount this off-center but wish the Kidde engineers had asked a builder or electrician what might work or at least made a standard mounting plate that fit their entire line of smoke detectors or maybe took a look at some of their prior designs. What could have been a 30 second replacement turned into nearly an hour.
