It has only a photoelectric sensor, which normally will mean that it is more effective in detecting smoldering fires rather than fast burning ones and that's exactly the performance that Consumer Reports found when it tested the first generation model. However, the current, second generation Nest has a unique Split Spectrum sensor that's said to be more effective than the norm for photoelectric technology. However, we did not spot any rigorous testing to verify that claim, so for now, consider this to be a standard photoelectric unit. Likewise, expert testing of the CO side of things is limited. No one has rigorously tested the CO detector performance of the second generation model. Consumer Reports says that the first generation Nest Protect worked well as a CO detector, though it was more effective in sounding an alarm when it spots high CO concentrations than low. User reviews, once mixed, are now much stronger as the product has been updated and tweaked since release. 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.
