The five things that actually matter
Forget star ratings. These are the criteria that separate a bowl that lasts three Nordic winters from one that cracks in November.
- CE certification (not just FCC/ETL — those are for the US market)
- Cord jacket flexible to at least −30°C — cheap PVC cracks at −15°C
- Steel-armored cord sleeve — winter + bored dog = chewed cord
- Wax-bulb (not electronic) thermostat — survives temperature swings better
- Sealed, potted heating element — no exposed wiring inside the base
