Doesn't leave any taste in the water.

Thirty tablets last me the majority of a two week hike or trip, more if I have taps along the way.
The case is bulky and weighs a bit (I try to reduce all needless clutter and weight, even the box). I take them out and put them in a sandwich bag or much smaller container somewhere they can't be crushed.

Does what it says on the Tin! It makes Water, safe to drink!
It makes more sense to buy a Water Filter, instead of these tablets! A Water Filter is more cost effective and you don't get the taste of the tablets!

Gives more confidence when drawing water from mountain sources especially lower down the hill. Water remains peaty and didn't clear, but didn't expect that. Never tasted the chlorine. In the past, have found dead deer in the stream uphill so a sensible insurance. Can't comment on quality as didn't chemically analyse the tablets - hope they got it right!
One sheet of tablets had a "blank" where there should have been a tablet but there were plenty in the pack - very small and weighed almost nothing.
