Rated 2.0 out of 5.0 by Verified Reviewer Dim LED's and Loose Battery Compartment
The green power LED is extreamy dim. I was installing this on a sunny day and could not see that the green power LED was indeed on indicating proper connection.
The battery compartment latch is poorly designed and hangs out unless the latch lock is installed. the directions indicated the latch lock as an option in a houshold but you clealy need to use it to get the compartment securly closed .
The directions DO NOT indicate the positive + and negative - terminals in the battery compartment so if you remove the battery and do not note it's orientation you will need to use a flashlight and magnifying glass in order to see the + and - indicators DEEP within the battery compartment.
The directions are overly complex and don't clearly indicate where the power LED vs the alarm LED are located.
Why is 2016 are these things still so poorly constructed and designed?

We have a few of these throughout the house and they go off every single time I cook something. I'll even turn the hood on and open windows and doors to vent, but I could be making a piece of toast and without fail the smoke detector goes off. I live in a townhouse, so I'm sure my neighbors probably hate me.

These were replacement smoke alarms. The previous product was no longer manufactured. To install this alarm the bracket had to be replaced but it was simple and the existing electrical connections matched the replacement alarm and plugged in with no modification

Rated 5.0 out of 5.0 by DanTX Replace BRK 4120B smoke alarm with BRK 9120B model
Ordered six BRK 9120B smoke alarms to replace our old BRK 4120 alarms. Very simple. Just unplug the old and plug in the new. The mounting brackets (collars/rings) are just as easy to replace. Do that first. All you need is a screwdriver for them. Couldn't have been any easier.

Old ones lasted 9 years. These fit exactly on previous brackets installed in minutes. Even came with batteries.

The product was exactly what I expected. Moreover I was treated with respect by Justin , an ASM . He greeted me, respectfully asking the purpose of my visit to his "HOME DEPOT" . Justin assumed ownership and I believe would have found a solution for anything I presented. Actually he was not disappointed when I told him that was there to pick-up an on line order. He escorted me to the cashier area and from a short distance observed the transaction. I my opinion, not that you care, this young man should have long a career with THE HOME DEPOT in either merchandising or training.

Used free shipping to our local Home Depot; the pickup process worked great. This was a replacement smoke alarm, so installation was a snap...the alarm includes a 9-volt backup battery. Tested the alarm after installation and it has given us no problems (e.g., false alarms, etc.) for a couple of months.
