The Baby Brezza Bottle + Breast Milk Warmer is the only warmer with two warming modes to safely warm breast milk and formula. It features a Warm Water Bath to warm or defrost breast milk, which protects its nutrients, and Steam Heat to rapidly warm formula or baby food. It’s easy to control – just select your settings on the LCD control panel and the warmer picks the warming time, alerts you when finished, then automatically shuts off. BPA-FREE; 1-year limited warranty.
