User Review: MSR MiniWorks
Price Paid: $40
Excellent water filter, easy to clean and is compatible with all Nalgene and MSR water bottle threads. Its strong point is its construction, which has not been compromised to get a lighter weight. Very sturdy pump lever and overall build, one of the few pump-type filters I've used that didn't break after the first trip (the Marine Corps adopted the MiniWorks for its recon units). Try it, you'll love it.
