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: Easy install, competitive price. Well known manufacturer. - We were getting tired of false-alarm smoke detectors and having them all sing out in unison. Also, getting tired of replacing expensive 9v batteries each year for the 7 of them. This smoke detector has a 10 year battery, loud alarm and easy installation. We opted for the battery only model and tucked the low-voltage wires away underneath the mounting brackets. If the brackets aren't drilled for your wiring box dimensions, they're easily modified with a drill using a small drill bit to drill guide holes and then expanded in diameter with a larger bit to the size needed. Once the base plate is mounted, just turn the detector on the base a quarter turn. The battery is activated with a chirp. A quick button test to make sure it's active. That's it. I'm not a wiz at the mechanics, but the advertisement says that this model reduces false alarms by using traditional as well as visual tech in order to determine an actual fire or smoke danger. So... set it and forget it (with whatever test schedule is right for you) and don't worry about them again until 2035!

## Features

- ENHANCED SENSING TECHNOLOGY: Reduces false alarms often caused by cooking. Comprehensively tested to meet the latest UL standards, meets UL 217 9th Edition and FCC standards.
- SELF-TESTING ALARM: Internal components ensure alarm is always operating as expected. Not a substitute for a manual push test, perform a button test once per week to verify alarm operation.

### ⭐ Didn’t last 4 months for a 10 year battery.
*by G***P on April 10, 2026*

I do not recommend this product. Within a month, one of the detectors started beeping indicating the battery was bad. Instructions said it would have to be discharged even though it was supposed to last 10 years. The second detector lasted a couple months longer after the first detector and the same thing happened. It too had to be discharged for the battery. I will never buy a smoke detector of this type again or this brand, very expensive for them not to last one year. Maybe I can get the third one to last more than a couple of months.
