Baby Brezza Instant Warmer is a revolutionary way to make a warm baby bottle instantly in 1 easy step. The Instant Warmer dispenses warm water on demand 24/7 and maintains the desired temperature all day and night- so it’s always ready when you need it. No more waiting 3-5 minutes for a bottle to warm up in a traditional bottle warmer or milk warmer. Just press the lever to dispense warm water in your bottle, add formula, mix and feed in seconds! Customize for your baby's liking by choosing from 3 temperature settings, while warming more safely than an electric kettle: Body Temperature, Warmer Than Body Temperature, and Room Temperature. The airtight water tank holds 50 oz – enough for an entire day’s worth of bottles. This premium water warmer works with all brands/types of bottles, including glass, plastic and silicone bottles. 1 year limited warranty (not valid if shipped or used outside the US).
