The Baby Brezza Bottle + Breastmilk Warmer is the only warmer with two warming modes to safely warm breastmilk and formula. It features a Warm Water Bath to warm or defrost breastmilk, which protects its nutrients, and Steam Heat to rapidly warm formula or baby food. Plus, it's easy to use - after choosing your settings using the LCD Control Panel, the warmer will choose the warming time, alert you when it's finished and then shut-off. BPA-FREE; 1-year limited warranty.
