I don't think a $100 premium is worth that especially considering placement can solve many of those issues. What WOULD be worth the $100 premium is if the sensors combined with the Nest thermostat could give me a better picture of my environmental health settings in the household or workplace. However, I don't think Fadell & co are prepared to launch something like that yet. I'll pass on the Protect and wait for something else. The nest thermostat on the other hand is one the top of my list if/when I get my own long-term home.
