I have selected the product primarily because of the design. I bought 6 pieces, and 5 installed in our new building, after all dusty work was completed in house. A smoke detector I have already for several false alarms (also like at night) now replaced by the "other" Sixth. But who has already made RambaZamba. I am therefore not very happy with the product and will probably start in the next few false alarms, the detector in question (now 1.5 years old) replace it with another manufacturer.
