Review title: Guess I didn't know any better
Product review: When my wife and I first received and used this warmer we thought that this was a great product. Over time we soon realized that boiling the water to cause steam that heats the bottle is not optimal. It leaves a water residue on the bottle and more so on the warmer itself. We even tried using distilled water. It was not until we tried the Avent warmer that we realized how the two are very different.
