Slim enough that guests never mention it

Sits flat against the ceiling like a proper fixture, not a hockey puck. 12 weeks in, zero nuisance alarms near the kitchen — the photoelectric sensor is the right call.

Great value for the money

Cheapest serious upgrade to our home safety so far. Arrived undamaged, mounting hardware bagged, manual actually readable.

Marcus T. · Austin, TX ✓ Verified buyer
★★★★★
Replaced every old alarm in the house

Bought one to try, then ordered more for the bedrooms. Battery life is honest, the low-battery chirp is documented, and setup took ten minutes.

Installed in minutes, tested the same day

Mounted it in the hallway before dinner — two screws, done. The test button chirped loud and clear, and it has run 6 weeks without a single false alarm.
