Mike Milferwrote a review of MSR SweetWater Microfilter on May 1, 2010
LOVE IT! Almost as much as my Hiker Pro which weighs the same but filters a little faster. Our team had access to NEW SweetWaters all summer and 100% worked perfectly. We made sure all the plastic components were installed correctly & tested each one of them at home before we left. This is a crucial step to test critical gear before venturing out which some people forget about doing. Luckily, no one had any problems and we were dealing with disgusting water conditions. The MSR SweetWater turns pumping water into a really, almost enjoyable, chore.
