I just installed these 2 First Alert smoke detectors, so I can’t give you a long time use review, but I’m happy with my purchase. These replaced two 10 year-old similar First Alert smoke detectors that had reached their expiration date. I was very pleased with those, which is why I looked for the same smoke detectors. I couldn’t find the exact same ones, so I replaced with these, which look similar and are basic like the first pair. Although the size of the new ones are a little bit smaller than the ones they replaced, I was pleased to find that the new brackets fit the 2 screws I already had in the walls from the old ones. I was concerned that I would be patching and drilling, but I didn’t have to, so installation was easy peezy. The other thing that is different on the new ones is that the batteries are 9 V versus the AAs for the old ones. I prefer AAs because it’s a battery that I always have around the house and they are easy to come by and inexpensive, relatively speaking. However, the new detectors came with batteries, so I don’t have to worry about replacing them for another year. Read more

Good band for your buck! Arrived in less time than estimated. Install is straight forward W/ nothing more than a Philips screw driver. At the cost point, these were the best value I could find. I would recommend them. Read more

It looks to be in perfect working order. It came with a plastic tab blocking the battery from discharging. You have to pull it out to get it to turn on. Not very hard to do, but someone with dexterity issues may need help pulling it out. It beeped when the battery was connected upon pulling out the tab. The test button seems to work. Haven't had any smoke yet to make it go off, so can't start to that yet. I was able to twist it into the mounted frame of the previous fire alarm. (Can't recall if it was the same brand) Read more
