John Striker: Very fast shipping and packaging is just like the picture but haven't opened or tried them yet so will have to wait and see. I did read adding vitamin c in the water can help neutralize the iodine taste but only after 34 minutes when the iodine is finished working/purifying.

Some other comments about it on the internet....

The chemical name for vitamin C is ascorbic acid. When Iodine and ascorbic acid are combined in solution, a chemical reaction takes place. In this chemical reaction, the ascorbic acid molecule loses electrons, which are transferred to the iodine molecule. Chemists call this type of reaction an oxidation/reduction reaction (or redox reaction for short). The ascorbic acid is oxidized to dehydroascorbic acid, and the iodine is reduced to Iodide ions. Oxidation-reduction reactions always occur in pairs like this. The molecule that loses electrons is oxidized, and the molecule that accepts the electrons is reduced.

Guess what else - it is an instantaneous chemical reaction. The ascorbic acid...

Andrew Oh: There are two major approaches to purifying contaminated water: you can try to trap sediment and microorganisms via a filter, or you can use various methods to sterilize the water by killing anything living in it.

For absolute safety, some recommend doing both, so I'm not going to sit and compare tablets to a pump filter, as they are different mechanisms of purification that aren't necessarily competitors. In fact, regardless of how you kill the bugs in your water, I recommend at the very least running the water through a cloth/bandana first as a first step in removing dirt and larger microorganisms.

That gives these tablets three major competitors...

The first, and cheapest, competitor is good old-fashioned boiling of water. In fact, boiling kills most things that some chemicals might not even get to. The downside, of course, is the need to start a fire, wait, and boil water. Good if you're camping overnight and prepping for the next day, but not so great if you need to fill up in the middle of a several-hour trek. If you're the kind of person who carries a mini-burner and a stove-top anyway, you probably don't need these tablets.

The second, and most...

JNieporte: These do what they're supposed to do. Before I give a review, I'll quote the box on a few points.
1. For use only when drinking water is suspected or known to be bacteriologically substandard. Not to be used on a continuous basis. (Their website suggests a six-week limit.)
2. Unopened bottles should remain effective for four years. (Look at the bottom of this review for how to date your tablets.)
3. We recommend that you do not keep an opened bottle for more than one year.
4. 2 tablets make one quart of bacteriologically water suitable to drink.
5. Proven effective against Giarda Lamblia when used as directed.
6. Has not been shown to inactivate Cryptosporidium cysts.

In a nutshell, use according to the directions and you'll be just fine. The bottle contains 50 tablets; you use two per quart of water. In really murky water, I use three. The active ingredient is Tetraglycine Hydroperiodide 16.7% and each tablet contains 6.68% of Titratable Iodine. This is the same stuff that I used in the military, but just to be sure, I opened a bottle and got three quarts of water from the Ohio River. Murky stuff. The first quart was treated with just the Potable Aqua...
