Query: A must have!

I bought this for my daughter before she had her first child. I am ordering it again as a shower gift. My daughter says there are two absolute must haves for her: mylicon and this warmer with the cooler for extra bottles. She doesn't have to leave the bedroom to prepare a bottle for my granddaughter and by the time her diaper is changed, the bottle is warm. Read the instructions and pay attention to the amount of water you add to get an even temp each time. Absolutely gets 5 stars.
