Perhaps it would be more convincing if these reports weren't over 3 years old. I own multiple Nest Protects, with no issues whatsoever. A year ago, I got pinged on my phone while we were out and about about a CO leak. Turned out we'd forgotten to turn the stove off. Without that ping, we'd probably only have come home a couple of hours later. That alone is worth their cost to me.
