Rated 5 out of 5 by jarhead822 Easy retrofit
Purchased this unit to replace a 10 year old unit that has been discontinued. The information on the site was accurate so all that I needed to do was mount the new ceiling bracket and connect to the existing wiring. The whole process took 15 minutes.

Rated 5 out of 5 by sp9239 Great Product, Excellent Price
I purchased about 10 couple years ago and they all still working. Purchased about 10 more in Dec to replace very old units. The wire and battery option is required for me so it fits perfectly in the hotel rooms.

Rated 4 out of 5 by md55 Great dual purpose smoke detector
I bought these to replace 12 year old units. I bought both the hard wired with battery back up and battery powered only units. I much preferred these dual powered for installation and maintainability. I would have used them in all locations had I known the quality of these units at the time of purchase.

This detector was a direct replacement for my old unit and was easy to install as advertised. No more false alarms in the middle of the night! Updated styling looks great too!

Rated 5 out of 5 by rbprivate1 Excellent product at any price!
I bought these to replace old Firex detectors that I installed during construction in 2002. Your detectors need to be replaced at least every 10 years. These are a great choice.

Rated 5 out of 5 by OhGee EXCELLENT VALUE, EASY TO INSTALL
I purchased three of these to replace the old BRK 4120B detectors in my upstairs hallway and sleeping rooms. If you are doing the same, you will have to take down the old mounting bracket, as the 9120B will not fit, however it's as easy as loosening two screws and rotating the old bracket out, and putting the new one on. The wiring harness is the same, so they are literally plug-and-play.
I haven't been able to find these locally at the low price that 1000bulbs sells them for, so I will purchase another three soon, thus completing my home's smoke alarm updates.
