Seth Wiscombewrote a review of Nuun Single Tube - 12 Electrolyte Tablets on May 13, 2014
Familiarity: I've used it several times
Got them for the easy electrolyte boost. I always seem to drop them in water bottles that are too big, (i.e. nalgene) so they end up being pretty watered down, kind of like that lemons and water wedding punch you drink just because it's there. I'm sure they taste better with the recommended 16 oz bottle, but these are just so convenient I can't help it, just drop it in and go.
