Rated 4.0 out of 5.0 by Dylan Adapter does work to older smoke alarm wiring, but may require aggressive rework of new mounting plates
My home was build in 2000, and featured 10 hardwired Firex branded alarms. 16 years later, I took a weekend to replace the original alarms. (fortunately I never needed them, but I felt it was wise to replace regardless.
To be clear, this adapter does allow you to retrofit older wiring (in my case Firex to Kidde), but the adapter does not fit into the new Kidde mounting plates. The most difficult part was to cut out sufficient amount of the new mounting plates to accommodate the large adapter plates. I used angle cut pliers and it did require some hand strength. I recommend a drill press or jig saw if you have one of those available. Please note, the mounting plate is still plenty strong even after removing a portion of the center to accommodate the new adapter.
The adapter did it's job, but the project took much longer than expected only because of the rework required to the new kidde mounting plate.

as in a previous review.....adapters will not work with kidde comb smoke and carbon monoxide detectors. The adapter hits the mounting plate and you are unable to turn the detector for mounting. Returned to HD. Called Kidde customer service but they weren't at all concerned. Just said they will not work with that model.

I had not realized that both adapters were not the same, so I didn't order enough.

Rated 1.0 out of 5.0 by BillD Very disappointed...product does not work as advertised
When plugged into the new Kidde detectors I bought to replace the FireX models I had (5 of), they
interfere with the new Kidde ceiling mounting plates. The center opening in the mounting plates is not large enough to accept the adapters. Because of this I had to remove the original FireX connectors and rewire the new Kidde connectors, a step I was trying to avoid in the first place by ordering the adapters.

Rated 5.0 out of 5.0 by Ricker Solved my problem
I'm rating the adapters five stars for being the solution to my issue. I wanted to convert my 10 year old BRK smoke detectors to new Kidde smoke detectors. Im rating the connection process 2 stars. It takes time and some finesse to say the least.Connecting the existing hardwire to the adapter can be a little tricky. Just take your time. It does work, but will require some good old patience for sure. The adapter clips into the new detector with not too much trouble. Its not a perfectly smooth/flush fit, but it works so don't contemplate too much. Don't try and push too hard or you could damage the unit. Last but not least, make sure you are using the correct adapter for the correct unit.

I replaced all my smoke detectors after 10 years. New ones did not connect to old connection. Found this item and decided to try. It worked. There are 2 differs sizes of adapters in each package, I used the larger of the two. I now have new smoke detectors that work

Rated 5.0 out of 5.0 by Lugwrench Makes replacing obsolete smoke detector super easy
Worth small cost as I did not have to shut power to tenants home office computers which were on same circuit as the smoke detector

Rated 4.0 out of 5.0 by AllThumbs adaptor works
The first adapter I broke. My bad. I did not have the grip strength to press the two side-pieces that snap into the receptacle to hold the adapter. I used pliers and broke it. I learned from that and the next two I used were a "snap". They went in easily enough and everything worked.
