Kids can get pretty thirsty, and quenching that thirst with pure juice can add up to a LOT of sugar. Natural sugar, to be sure, but more than most kids really need. This product seems to strike a good balance between juice and water for thirsty kids. The main reason I wouldn't buy it is due to the one-use packaging, which is why many parents DO buy it. So it will works great in that niche. And my kid was raised on (refilled) water bottles, with watered down juice at home. He lived, despite the depravation, to his current age of 31, and now drinks water voluntarily.

If you must buy packs of juice for kids, this is better than most. Better yet, teach them to drink water.
