Fire Alarms Smoke Detectors, Smoke Alarm Battery Operated,Fire Alarm with Test Button & Low Battery Signal, Photoelectric Technology Fire Detectors for Bedroom and Home (4 Pack)

Easy to install and good value for money.

Time will tell if they last 10 years but install with stick plates and magnets 🧲 I like a lot you can mount the normal way and these are little and less expensive than box storeVery pleased with them

Smaller than traditional alarms. Very loud. Easy install.

they have not gone off yet but they have been installed all ready , but I like the value for the money .

Purchased this 4 pack after one of our smoke detectors stopped working. Very easy to install as they came with sticky pads. They can be placed anywhere

Buen producto incluye hasta las baterías y las herramientas si las quieras colocar en la pared. De esos productos que la gente no compra y son tan beneficiosos para nuestra tranquilidad

The media could not be loaded.  The packaging was good and the set even included batteries and the mounting hardware.Unfortunately, the interconnect feature is not consistent and would either not alert the others or would alert two out of the three. The worst part is they did not alert when smoke was clearly present. I'm not a smoke detector professional but I'm pretty sure a smoke alarm should alert you to the presence of smoke as it's kind of in the name. As you'll see from the video I used a smoke pen to simulate a fire. In my testing, the alarm didn't go off 2 out of 3 times and the one time it did, was over a minute after smoke was present. I'd show those videos as well but I can only upload one video per review. I haven't tested many smoke detectors but I would avoid these.# UpdateThe company does apparently listen to reviews and reached out to me and offered to send a replacement. I responded and agreed for them to send out a working set. However, that set was returned to sender and I did not get to test its reliability.

I installed these throughout my home, they would not link up to each other. Seemed very cheaply made.
