Hello again forumers (and any chemists),

The latest tablets in U.S. seem to be the MP1's which sell at ~ $14 on most sites, but the P+P is terrifying. However, at Decathlon in stockport there are MT1's at £10. These are chlorine & silver based and I was wondering if
a) anyone has tested both
b) what's the difference in performance, effectiveness, time needed to clean the water
c) any way of finding out which one is better, healthwise, as that kind of info isnt easily found.

Many thanks to all that can help with this one. And to everyone that posts, thanks for the info and insights.
