Keep an eye on manuf date if buying in store

Would Recommend

Easy to replace my existing smoke detectors from the same manufacturer but because dimensions were slightly different, needed to replace bracket and pigtail connector. Couple of extra minutes per unit but not too difficult

Decent low cost First Alert replacements

Would Recommend

I got these because a couple of my smoke/CO alarms started to chirp from non-battery related causes. (They were about 13 years old and at the end of expected lifespan.) The install was a bit more involved than I anticipated because the connector plugs were different from the previous ones, but there was no hassle splicing in the new ones.
