The Air Swirl Waterless Bottle Warmer warms bottles safely and evenly. It employs waterless technology using only hot air to eliminate bacteria and scale build-up. This warmer gently rocks the bottle, preventing hot spots and ensuring uniform temperature. It warms breastmilk without overheating, safeguarding essential nutrients. Precise warming times can be selected via gentle-tap buttons, while the LCD display shows a countdown timer, beeps, and auto shut-off when finished. It also works with most bottle brands and types.
