Installed fine, seem to work, and flashing lite isn't a disturbance
They installed without an issue. Tested fine once installed.They do have a flashing light that goes off every minute to let you know they're working, and I was concerned about them being in the bedrooms. But the light is subtle enough that you really don't see it and it isn't disturbing.Without the house catching on fire, don't for sure if they'll work. Assuming they will.

No need to worry about batteries
I used to use the hard-wired detectors so that I don't need to change the battery frequently. This detector comes with a built in 10 year battery, so I no longer need to hard wire my detectors. I can just install it forget it. Plus it's very easy to install.

Not sure how its working
Very neat nice noise it makes. Sometimes it misses the stove smoke (like ten fifteen times) but like once or twice it went off while i was doing not much anything

Read the instructions carefully.
I bought two of these smoke detectors. I removed them from the boxes and removed the yellow tags as directed, but neither of the detectors worked when I tried to test them. I went through the Amazon process of complaining only to be told to contact the manufacturer via a telephone number provided. I talked to the manufacturer's representative and explained what I did. He told me that the detector had to placed into its ceiling attachment bracket before trying to test it. I did this and both detectors worked as required.I am quite satisfied with the detectors but the instructions could have been a little clearer.

Good value for replacement smoke alarm.
Easy to install. Good price. Arrived as per stated.I had to fiddle a bit with getting the mounting screws in place - for all of two minutes.Biggest problem with this purchase? Delivery driver did not shut gate behind themselves on the way out.

False Advertising
I bought eight of these in May of 2023 because description says 10 year battery life. They've all failed after only two years. I do not see a way to contact First Alert for product replacement support. Would not buy again.
