I too wish I had read these reviews regarding the Nest Thermostat. Isn’t it convenient that Google will not allow you to review their products on their website!! I suspect because most of what they do is crap and the reviews would show this. DO NOT BUY THEM! The quality is awful, but worst of all their Customer Services are not interested. I have the same issues that others have complained about, the heating and hot water coming on for no reason. Customer Services expect me to pay to fine out what the fault is. No other reputable company would behave this way.Google should stick to being a search engine. Their electronics equipment is crap. I have had 2 web cams, both failed, their Google Hub doesn’t understand you half the time, and the Nest Thermostats are just expensive rubbish.
