Myself and especially my wife are tech savvy. We thought the Google Nest would be a great option because Google has a great rep in the tech world and we wanted a brand new thermostadt with our AC and Heating system we had installed last June. It has been nothing but a pain in the ass s to set it up and has been nothing short of an headache ever since. It definetly has a mind of its own. It simply will not let you set it to a desired temp and be done with the damn thing. It is confusing to operate and the customer service is extremely hard to reach. You can control it manually thru your cell and see the temp as well which is good, but its still a pain in the ass because the system is continually shuts itself off trying to save you money. This is dangerous to us because we have pets and live in Florida and our house gets up to 10 degrees hotter than outside very quickly. Dont buy this piece of junk.
