I used Klearwater on my trip this past summer in the Weminuche and was very impressed. It is very foolproof (no mixing) to use as it takes 1ml of Klearwater to purify 1 liter of water. Twice while pouring the Klearwater from the bottle into the measuring spoon it overflowed, so maybe a dropper would be better suited. There is a cholrine odor but no taste. The shelf life is short compared to other products and a lighter bottle would be nice. It comes in a thick glass bottle. Overall, I really like it and will continue to use it.
