Review on SITERWELL 10-Year Smoke Detector with Photoelectric Technology, Built-in 3V Battery, Low Battery Warning and Silence Function, UL217 and GS508 Certified – Pack of 4 by Oso Mears

Bought and installed shortly after receipt. Today at one o'clock in the morning they started to walk. They were installed in <3 months. It is impossible to disable them. Right now it's lying under a pile of pillows trying to turn down the volume. Unfortunately it's Friday night and the garbage won't be picked up until Wednesday, so we'll have to listen to this until it's garbage day. And no, I checked the house about 5 times, there is no fire and no way to turn them off.
