Are the temperature presets actually accurate?

Reviewer experience is mixed and brand-dependent. Specialist pour-over and tea communities frequently note that mid-priced kettles can drift 3–10°F from their set point, while precision-focused gooseneck models that advertise ±1°F control tend to hold tighter. If exact temperature matters (matcha, light-roast pour-over), expect to spot-check with a thermometer on any kettle under about $150.
