Hmmm. Rather on the expensive side, and it appears to have a shelf-life of 3 years even if it is not used. Also, I don't think that a "sport drink" would be usable for cooking.

On the other hand, it is a reverse-osmosis unit. That means that is SHOULD work with even the dirtiest of water, maybe even contaminated or salty (but they do not say on the web site).

If not for the limited shelf-life, I would definately consider it.
