Source-linkedVerify source — Best Buy review

Best Buy 1-star review by lanibear (title: "The worst tech experience I have ever had"). Fought for a year to get it working: app pairing issues, repeated power drops, and internal temperature reading so high heat had to be pumped up, driving heating bills over $200. Google not helpful on replacement; switching brands.

Source-linkedVerify source — Best Buy review

Best Buy 1-star review by M1A2G3A (title: "Google ruined a once great brand / Product"). Nest thermostats burned out the PC board on a high-efficiency furnace, costing about $1200. HVAC tech said continuous power draw can fry the board; switched back to basic Honeywell units to protect the new board.
