■ The catch — co-equal billing, always
It does not heat the milk. No wand does — you microwave or stovetop-heat first, every single time, then froth. That is an extra step and an extra dish before every hot latte, forever. Only a carafe frother heats and froths in one press.

Phantom capacity
Carafe frothers froth only 4–8.5 oz at a time and heat 12–25 oz — the Aeroccino's ~4 oz batch is exactly one drink. Capacity is fixed per model; check the spec against your mug before you buy.
Hot or cold — not always both
Several carafe models do hot or cold but not both, or make only one foam texture (billowy cappuccino foam, not loose latte foam). Cold foam is now table stakes for iced coffee — confirm the setting list, don't assume.
Plant milk is a coin flip
Standard oat, almond and soy foam thin and collapse fast — barista-edition oat milks foam best, and results swing by model. Even the $50 NanoFoamer struggles with nondairy milk.
