It’s super convenient to have such a bottle warmer in the confinement. A pot of water can be used overnight. You can use it when you pick it up. You don’t need to go to the pump and use cold water to cool down. You can also make tea for yourself. At the beginning, I wanted to choose two. Later, I felt that this was enough. After all, the remaining milk powder took too long to drink, so I chose this simple one.
