User Review: MSR MiniWorks EX
Price Paid: gift
I had read good things so bought one after my previous filter wore out after about 5 years. Day 3 in the backcountry my new Miniworks EX malfunctioned. A rubber valve tore and it was completely irreparable with zero function.
I'm going back to Katadyn Hiker — lighter, faster pumping, and I've never had a problem with one.
