User Review: MSR MiniWorks EX
Price Paid: $89.95
one of the best filters i have ever used. i wont ever leave home without it.
the only time i had problems is when the only water i could find was nasty pond water with a lot of slim in it. then it required me to clean it every few liters.
no problems since, actually i just boiled it to sterilize it and it looks brand new.
