Would Not RecommendLIke others, I bought these due to the great rating by a popular magazine, as well as the dual censors. Replaced all 14 detectors in my home- not 2 months later started getting a false alarm in my daughters bedroom. Took out the detector and placed it in another spot and the next day, got another false alarm. The detectors I replaced had worked for 10+ years with no problems. Looking at other reviews, this seems to be a known issue that hasn't been addressed. I don't trust these now.
Dual sensors for safety!
Would RecommendThis type of detector is the way to go because it uses both photoelectric AND ionization sensors, so it will detect both flames and smoke.

Good alarm
Would RecommendAlarm was very easy to wire and mount, it also reacted almost immediately to a small spritz of smoke detector spray, and all the extra features will definitely come in handy. I am giving four stars due to the fact that the alarm I bought was manufactured in 2021, two years ago. That's a bit older than I would have liked. I have battery operated alarms that were installed months ago but were manufactured sooner.
Probably good. Cheap, inoperable battery door
Would Not RecommendI bought three because they were the highest recommendation on CR. I went to install them today, and the battery door on the one I opened was hard to open, I was afraid it would break. I finally got it open, but then it wouldn’t close, even with very hard pressure. I didn’t want to break the cheap plastic, so these are going back. Changing batteries shouldn’t require feeling like you are going to break the battery holder. Very poor design on that.

Unsafe Product with POOR Quality
Would Not RecommendBought one 3120B dual smoke alarm 10/18 along with 6 other models for the entire house. Being an engineer, I came to appreciate very much that the 3120B uses only 2 AA backup batteries. Every year at battery change time I have to swap out the 9 volt batteries on the others but not the AA's on the 3120B; I always measure and record the beginning and the ending voltages on every battery-yeah, engineers do that kind of thing. So, when daughter's house needed 6 new smokes I bought the 6 pack of 3...
