It seems like the majority of people who had problems with the Nest Thermostat in these comments had it hooked up to a heat pump system. Mine is a first-gen, bought the instant they were available to the public, and it's been rock-solid for the past 3+ years. However, I only have a standard central air and central heat (gas furnace) setup here in Texas. Nothing complicated. I've been debating the Protects myself, the battery operated ones.
