First Alert Smoke Alarm, Battery-Operated Detector with Test & Silence Button, SMI100, 1-Pack

I needed a replacement for an old smoke alarm that stopped working, and this First Alert model was a perfect choice. Installation was quick and easy—I was even able to use the same screws from the previous unit, which made the whole process hassle-free.The alarm is compact, has a clean look, and the test and silence button is a nice feature for peace of mind. Battery-operated and ready to go right out of the box, it started working immediately after installation.Great value for a reliable, no-fuss smoke detector. Definitely recommend it if you're looking for a simple and effective replacement!

Works exactly as advertised. I use these frequently across multiple properties. They're easy to install, very reliable, and cost-effective. Great value for the price. I highly recommend to anyone needing a simple and dependable solution.

This smoke detector is a great price, installs easily and works great!

Works a little to well had to move the toaster it kept going off every I made toast

Don’t put it next to a vaporizer. This is a very sensitive smoke alarm. I have a vaporizer in the bedroom and I hooked this up in the bedroom, but it seems like the vaporizer sets it off. But other than that, it’s good.

I have used these exclusively in my home and they will alarm as advertised . They also give off warning beeps when the battery gets low on charge. Battery included with these smoke alarms. I have one wired smoke alarm but power surges have damaged the wired 120v unit in the past so the battery models are not affected by power surges . Batteries will last about 18 months . Most people die in house fires from smoke so smoke alarms are very cheap insurance to awaken you at the slightest hint of smoke giving you time to escape .

Kind of hard to review something that hasnt saved your life yet...It feels like its made of quality materials especially compared to the 16 year old smoke alarm it will be replacing/working along side.I like the drawer pull out for battery replacement. But as I have arthritis in my hands I found it a little bit hard to get the drawer out and the batteries out. Went in easy enough. That being said it was a LOT easier putting in the two AA batteries than finagling the old alarm and its 9v battery compartment.Comes with everything you need to mount except the screw driver and drill if you like to pre-drill.I would purchase again. Test seemed to work. But only time will tell, as with any sensor/alarm when there is something for it to sense and go off about. I believe it was rated well in consumer reports but do not quote me. Always check for yourself as this varies by year.I got this one because my old one is a smoke alarm only and I wanted to have a dual sensor smoke detector fire alarm. no, sensing smoke is not the same thing as sensing a sudden flame up. Smoke is smoldering and a sudden flame up doesnt necessarily have smoke to set the alarm off. Plus learning my old alarm is 16 years old made me feel a little iffy. Apparently some smoke alarms are guaranteed for 25 years. Not sure about the new one. Newer ones seem to be good for 10 years rather than 25. But I feel safer knowing both the old and the new are on board.Maybe more than you wanted to know but I thought if you are like me and you did not know that there are two types of alarms regarding possible fire you might appreciate the TMI.Cheers!

easy to install, cheap and effective for peace of mind.
