💬 What real owners actually say
Synthesized from 2026 owner reviews & discussions across social media — the things spec sheets leave out.
One on every level. Place alarms on each floor and in or near every bedroom.
Interconnected saves lives. When one alarm sounds, all sound — you hear it anywhere in the house.
Combo smoke and CO. Combined units cover two invisible dangers in one device.
Dual-sensor. Photoelectric plus ionization catches both smoldering and flaming fires.
Test and replace. Test monthly; replace alarms every 10 years (sensors expire).
Each slider sets how much each criterion matters to you (0 = ignore, 10 = critical).
