I was sent three bottles in the mail as a sample, and happily drank them all in a day. The sparkling water has zero calories and no sweetener, and it's been flavored with things like cinnamon, orange peel, lemongrass, mint, vanilla, and lavender. Unlike Metro Water and a lot of other flavored water products I've tried, these don't taste like mouthwash, but rather are restrained and more aromatic. Sort of like tea, but water. They come in plastic single-serving-size bottles, or 25.4-ounce frosted glass bottles that are dinner party–suitable. And of course, you don't have to be pregnant to enjoy them. But it's nice to have them if you are.
