Title: Inexpensive Smoke Detector
Review: My smoke detector dropped dead just as I was about to change the 9V battery. This was a great inexpensive replacement that arrived the next day. Works perfectly.

Title: Excellent Value
Review: First Alert SM100 Battery Operated Smoke Alarm 3-Pack. I bought these to replace my 3 old First Alert smoke detectors that reached the end of their lives. They're a "Contractor's Pack" since they arrived in a plain cardboard box inside an Amazon Prime shipping carton. All 3 detectors were Made in Mexico and are dated 2024 JUL 25 L9, so they're fresh. The included 9 volt heavy-duty battery is Made in China by BP. I'll replace it after it dies with a 9V alkaline battery.The new detector is similar, but not identical, to my old one. Because the new detector is a little larger in diameter, it won't fit into the old base. Note that I didn't have to relocate the screw holes to align with the new base plate. That made installation very easy - the new base plate fit over the old screws. Good design, First Alert! I didn't expect that.Time will tell if they last as long as their predecessors. Assuming that they will, I give them 5 stars!

Title: Super easy to install! No Batteries Needed!
Review: We bought these to replace older smoke detectors in our home. They were super easy to install. You just pull a plastic tab out of the detector to initiate power and all you need to do after that is install the bracket and twist the detector in.Note that the screw holes on these probably won't line up with where your older detector screws were. These space between the two screws is a bit more narrow than our previous ones so like us, you may need to drill new holes.

Title: Recommended for everyone
Review: Sure! Here’s a review that incorporates statistics to emphasize the importance of having a smoke and carbon monoxide detector:I recently installed this smoke and carbon monoxide detector in my home, and I can’t stress enough how crucial it is. Did you know that according to the National Fire Protection Association (NFPA), three out of five home fire deaths occur in homes without working smoke alarms? That's a staggering statistic, highlighting just how important it is to have reliable detectors in place.Moreover, carbon monoxide is often called the "silent killer" because it’s colorless, odorless, and tasteless. The Centers for Disease Control and Prevention (CDC) reports that around 400 people die from unintentional carbon monoxide poisoning each year in the United States. This detector provides a critical line of defense against such a deadly threat.Not only does this model meet high safety standards, but it also offers peace of mind with its reliable detection features. Installing it could be the difference between safety and tragedy. Don’t take any chances—protect your home and loved ones with this essential device. Highly recommended for every household!

Title: First Alert is the Safer Choice
Review: This is my second purchase of a First Alert Dual Sensor Smoke and Fire Alarm. I turned to this product after I found that the Kidde smoke detectors installed as part of the real estate transaction on the purchase of my new home were complete duds.I want to take this opportunity to point out that in some states it's no longer possible to buy a conventional battery-operated smoke alarm. I am glad Amazon did not prohibit the shipping to California, where I live, because I am absolutely convinced that our clueless legislators have created a public safety hazard by forcing the sale of smoke detectors to rely on 10-year (non-replaceable) batteries. Because I had "new" smoke detectors installed in my home and because the "Push to Test" feature worked, I could have been clueless for as long as 10 years that they were in fact inoperable units. The only reason I learned otherwise is because I nearly burned down my house using a vintage toaster (my bad) the second week after I moved in. I thought it was a fluke that neither of the Kidde smoke alarms went off since they were located in bedrooms (not the kitchen). But then I had a near miss a few weeks later when the damper (newly installed!) stuck closed on first use of my fireplace. In that instance, the entire house filled up with smoke to the point where I had to open all the windows and doors in the dead of winter and evacuate myself (asthma) and my pets to let the smoke clear. Again, the "new" Kidde smoke detectors with 10-year batteries failed to emit a single chirp. Further testing would reveal that even burning a paper towel with a lighter an inch away would not provoke the Kidde smoke detectors to sound an alarm.The problem with forcing consumers to rely on 10-year safety devices that are built to cheap Chinese standards is that they can be defective for that long and consumers may not be the wiser because the longer they stay in place and the less attention they require — i.e. to change out batteries on daylight savings as is the usual practice with a conventional smoke detector — the more likely it is that consumers will miss the fact that A) their device is defective or B) 10 years has lapsed and the battery is dead.I hope other States do not follow California's lead and that this dual-sensor smoke detector is not discontinued. Thanks to the wake-up call with the Kidde detectors — which relied on a single-sensor design — I performed the same paper-towel test with these First Alert smoke detectors and they passed. At the same time, these are not so sensitive that they produce false alarms.The reason I turned to First Alert was because I contacted Kidde in the hope that they would consider recalling the smoke alarms that did not work in my home. After all, what are the odds that not one but two would be defective? They agreed only to replace my smoke detectors — but they took TWO MONTHS to ship me the replacements, which was an unacceptable length of time to go without a working smoke detector in my home!If anything, my advice to politicians who are considering making laws about safety products of this type is that they mandate a dual-sensor design — but continue to give consumers the choice as to whether or not they prefer to change batteries annually or take their chances with the 10-year variety.Thank you, First Alert.
