Cons

- White-label brand with an Amazon-only presence and no US service network
- A few owners report the unit freezing up / not heating in cold air — the heat-pump ~50°F floor, not a defect
Freezing up and refusing to heat in cold weather — which is the roughly 50F heat-pump floor rather than a fault, and applies to every heat pump on the page.
