system smoke detector
It currently earns a 4. 6 star rating following nearly 6,000 reviews at Amazon. While there are other smart smoke detectors available, none that we spotted have received the positive feedback that we saw for the Nest Protect. For example, the First Alert OneLink Est. $110 looks to directly compete with the Nest, but both expert and user reviews are underwhelming. Among other issues, both CNET and Wirecutter note shortcomings in the connected features, including slow response times pushing notifications to the iOS only app and for the app to silence a nuisance alarm.
