The short answer

Both are cordless flasks that heat the milk itself, so with either one you pour milk in, warm it, pour it into a bottle and wash the cup afterwards. The Brezza is the quicker and more precise of the two. Baby Brezza quotes 240ml to 37C in about three minutes, you choose from four set temperatures with a live readout, and it beeps and switches off when it's done. It also takes a filled 180ml milk bag. The Momcozy's selling point is size: it holds 500ml, nearly twice the Brezza's 270ml, though Momcozy gives less detail on temperature control. It costs around £90 against £130.

Both are also marketed for warming water for formula, but water at 40C won't kill bacteria in powdered formula. Use either for breast milk or ready-made formula, and the NHS flask method for powder.

My call: the Brezza if you're warming expressed milk away from home every day, because speed and control are what you're paying for. The Momcozy if you need a lot of milk in one go, say for twins, or the extra £40 is hard to justify.
