My house was exclusively formula-fed, so this was especially helpful at night!! No box or instruction manual. I've included photos of it running to confirm it's working. For those who want this, I understand you'll want it quickly, so I promise to ship it within 24 hours. Milk warming, steam sterilization, baby food warming, rapid defrosting, rapid heating, touch panel, dry-boil prevention, automatic shut-off, and a backlight that's easy to see at night.
