Negative Positive
Title: spurious alarms
Review: Ordered nine of these smoke alarms last summer, replacing older units. We haven't had a fire, so I can't say how well they work in that scenario, but we had to replace one of them after about a year because it started sounding brief alarms for no reason in the middle of the night. Since all nine are interconnected, they all sounded. It was rather unsettling. The replacement has been fine so far, but a couple of days ago another unit initiated one brief spurious alarm, so now I'm keeping my eye on that one.
Is the review positive or negative?
