> Failure to detect smoke Incorrect. If you examine the announcement you linked, the issue was a failure to alarm when smoke was detected (below UL's must-alarm threshold, above which the Protect ALWAYS alarmed) due to false detection of a hand-wave as part of the "Wave to Hush" feature. This feature was remotely disabled on all Protects via a software update. > False alarms. Not for a long time. The second-gen Protect, which has been out for years, includes much-improved smoke sensors and algorithms. This is reflected in its unusually-high 4.6 star Amazon rating [0]. > Those are Nest's worst product. How did you reach this conclusion? In addition to its outstanding score on Amazon, the second-gen Protect is frequently recommended by professional reviewers [1][2][3]. Anecdotally, I have 3 first-gen Protects in my home (in addition to 2 second-gens) and have never had any false alarms (except when I forget to run the fan while cooking bacon, and fill the entire house with smoke...).
