Smoke Detector, 10-Year Smoke Alarm with Photoelectric Sensor and Built-in 3V Lithum Battery, Fire Alarm with Test Button and Low Battery Warning, Fire Safety for Home, 2 Pack

Peal off the film and stick one magnet to the wall, peel the film off the other magnet and stick to the back of the smoke detector, then stick the magnets together. That's it you're done!!!

They are small in size which Is nice. The test sound is a low beep an the actual alarm is pretty loud. For the price an free shipping they are or seen to be a good quality tho i hope to never find out

Bought smoke detector was on vacation when they arrived. activated and tested smoke detector according to instruction. Did an actual smoke test device failed to activate. (4) came in the box none of them detects smoke. Please is there a way that you are willing to replace the non working items. Was on vacation for over a month and came back to items not working and the 30 day return policy have seen to run out. You just Can't take a person's money like that and think that it's ok.. confused on why we have not resolved this problem from your end...

This was the easiest fire alarm to install and get price for the money

Easy to install and keeps an ear out of any problems.

My cat meows louder that the horn on these things. WOULD NOT RECOMMEND THIS ITEM.

I thought these were the perfect size and were a great value for your buck, but not if it doesn't pass county inspections. I purchased and installed them, then 3 months later a county inspector needed to check smoke carbon monoxide alarms for a permit project on my home. The smoke alarms did not pass. The noise was too weak. I could hear it just fine, but they want ear deafening alarms installed. Just something to think about, when you purchase. Only happens in CA.

Liked very well easy to put up with 10 year battery life.
