Title: They all go off at once!
Review: These things are horrible! The units we have are under 4 years old (installed when the house was built) and they go off in the middle of the night for no reason... the worst part is that if 1 unit goes off, the rest sense it and they ALL GO OFF! The result is running around the house at 2am ripping every one of them out of the ceiling. After last night... 3rd strike and they are out! I will be replacing every single one of these things with another brand!
