The Nest learning thermostat learns from you and programs itself, so it is cooling and heating more efficiently and saving you money. Plus, it can be controlled from anywhere on earth through your mobile device. So coming home from vacation no longer means coming back to a blisteringly hot house. Nest claims that on average people save 10% to 15% on heating and cooling bills, so this is one of those products that aims to pay for itself. Nest also works with “Alexa”. It averages 4.5 out of 5 stars on Amazon from over 4,600 people (84% rate it 5 stars, read reviews). It typically lists for $249 and is being discounted 20%, down to $199.
