Baby Brezza Formula Pro Advanced is the most advanced way to automatically make a warm, formula bottle in seconds. No measuring, no mixing and no fuss. You can customize the perfect bottle for your baby by dispensing 2-10 ounces in 1 oz increments, choosing 1 of 3 temperature settings or dispensing water only. It works with virtually all brands of formula and all bottle brands and sizes. This revolutionary machine is more accurate, consistent, hygienic & faster than hand scooping. NOTE: The level will appear higher than the ounce size selected because of added powder volume and/or variance in bottle markings. For example: 4 ounces of water plus powder volume is approximately 4.5-4.75 ounces depending on your formula powder type. 1 year limited warranty
