What's the best bottle warmer for breast milk?

Reviewers consistently favor water-bath (not steam) warmers for breast milk because they heat gently and are less likely to scorch nutrients or create hot spots. The Baby Brezza Fast and Philips Avent SCF358 both use water-bath heating and draw the strongest breast-milk-specific praise, while several high-trust r/ExclusivelyPumping threads warn that some one-touch units overheat milk if you don't dial settings down.
