Query: Great Warmer.

This product is absolutely wonderful. I bought this warmer after being given the larger one with the cooler as a baby shower gift. I wanted to use this one for travel and to send with to our childcare provider's house. This warmer quickly heats up a bottle even in the care using an adapter. You do have to play with the amount of water added to the warmer, but not much. The automatic shut-off is a life saver and makes it an ease to use. I am confident warming up my breastmilk in this warmer and I would recommend it to any family with a new baby.
