Review on White Hardwired Smoke Detector BRK 7010B with Photoelectric Sensor and Battery Backup by First Alert by Bob Fasho

Would give zero stars if I could. I moved into a house with 5 of them and they started walking at 3am. I estimated they were 8 years old so I wrote it down on the units age and bought another 5. Less than 2 years later the false positives started again. Today was my last straw as they screamed for no reason when I got home from work. God knows how long my poor dog suffered to hear this crap. I had no idea which device was causing the problem as they all worked which made me panic as I ripped them off the ceiling. I will NEVER buy this brand again and prefer to have a security system to monitor actual working smoke alarms that does not harm my family. I never leave reviews but I'm just so angry that what should give me peace of mind is now causing me stress and anxiety.
