Very easy to install because it's battery operated. No wires needed be plugged. Sound loud and easily audible. It could, however, in addition to detecting CO2 and smoke also detecting Gas. That would be a good improvement.

A terméket sehogy nem lehet beállítani! Új akkuval telepítve, DE ÖSSZE- VISSZA riaszt. Sajna megbízhatatlan.

The sensor is not costant

Perfeito O que comprei, recebi

Sieht gut aus, noch nicht getestet, hoffentlich bleibt es auch so. ;-)
