ArmyRangerRick,

I just noticed that you wrote that you got these from a US supplier. Why don't you ask your supplier if they are legal for sale in the US? And since it seems that Aquatabs aren't certified for sale as a water purifier in the US (and Medentech's website and Doug seem to bear that out), I'm curious why there is a US supplier for Aquatabs? That seems odd.
