User Review: MSR Miox
Price Paid: $129
I picked up the MIOX unit before going on a Mt. Rainier climb. It's easy to use and as long as you follow the directions and wait times it will give you safe water (from virus, bacteria, etc.).
It does leave a slight taste and as my friend found out the solution it creates will act like bleach to your clothing if you spill it on yourself. The only issue I've found it that the test strips indicate a "too low" for the standard treatment. I solved this by treating for one step higher than the standard. It may just be the water sources I'm using. I don't consider a fault of the unit as it does its job.
