## Customer Reviews

### ⭐⭐⭐⭐⭐ Perfect fit for old alarms
*by  on Reviewed in the United States 24 March 2026*

Easy to install, fit right on bases from old alarms. Plug in was exact match so no new wiring was needed. Also dates on new alarms were within the last 3 months, meaning they haven't just been sitting in warehouse after being manufactured. Really pleased with product

### ⭐⭐⭐⭐⭐ Easy to install
*by  on Reviewed in the United States 8 May 2026*

So far they are working great. Pretty good value. Easy to install.

### ⭐⭐⭐⭐⭐ Perfectly replaced the originals, wiring and housing
*by  on Reviewed in the United States 27 May 2026*

Just as I expected and a perfect replacement for the detectors in the house I bought. It’s nice the originals were in decent shape and the new fit into the housings.
