Nest Thermostats . It would seem that every company out there that makes a smart thermostat is trying to take a swipe at Nest. Either overtly or covertly the bashing goes on. I have had nothing but success with the product and my customers are very pleased with the ease of operation and performance. Forty five years in this trade has taught me not to overstate claims regarding savings of energy. I do not believe nest ever misled anyone in there claims. Similar claims were made by Honeywell when the first chronotherm thermostats came out. I happen to think that neat is the victim of a lot of professional envy. Many companies were late getting their product to market and suffered as a result. It is men like Tony Fadell that built this country. There contribution is immeasurable .
