Works great and fills quickly
This thing is awesome. The attachments for Nalgene bottles and quick release hoses make this a snap to set up and I believe it's actually faster than it's rated 1L/min flow rate. I can usually fill a 1L Nalgene bottle in 30-45 seconds. The pump is awesome and way less awkward than comparable MSR models with the standard pump design. This feels much more durable. UPDATE: I've used this filter for about 3 years now and had no problems with very minimal maintenance. Highly recommend.
