I know that drinking a lot of water is healthy in so many ways besides spurring weight loss. I'm also not much a water drinker, so I've used Mio (peach-mango flavor--yummm) for over a year. I'm favor of natural products whenever possible so just got this on amazon. It's supposed to be all glass/stainless. I tried some that a co-worker had made and it was good.
The idea is like a tea ball, only instead of tea/hot water, you fill a hollow insert with fruit, cucumber, mint, or whatever you like and then it sits in the center of the carafe of water and the flavor permeates the water.
I haven't deployed it yet, but am excited !
