Never let me down.
If you're looking for a pump style filter, this is the industry standard. Easy to clean, simple to tear down, and the only piece you have to worry about is the ceramic element (do not drop naked element). I use it when I am someplace with real silty water (I work around the Mt. Saint Helens blast zone) and I often have to clean it after 2-3 liters, but it just keeps on rocking. If you are in a long term camp trip in a place with fairly non-silty water I would purchase the MSR Autoflow as it requires no pumping and is a workhorse.
Buy this for dependability.
