Title: Perfect for high useage, very tough.
Review: This is an excellent heavy use filter. Tough, simple design and about 16 oz in weight. It filters out bad stuff and with a carbon inner filter makes water taste clean. This is my second MSR Miniworks, the first one lasted for years of tough use and abuse. The key for this filter's excellence is to clean it by back flushing(its in the directions and will help!). There are much smaller and lighter filters out there but for long term heavy use this gets an A+.Amazon shipped this very fast. Wow.
