I used it on a 2 day trip, and it worked well. But, I've decided to go with a gravity feed system.

The HyperFlow utilizes the latest Hollow Fiber Technology in a package so small and so easy to use it will change the way you travel in the backcountry. Its ergonomic design, diminutive size and tool-free maintainability make it just as appropriate on day trips as it is on multi-day excursions. Also included is a Quick Connect Bottle Adapter™ — allowing direct connection to all MSR hydration products and a variety of other "wide mouth" containers — and an advanced prefilter to prolong the life of your filter.

High Flow Rate: Pumps more than 3 liters per minute or one liter every 20 strokes.
Ultralight: Just 7.4 oz. (209 g).
Ultra Small: Just 7x3.5 in. ( 17.8 x 8.3 cm) makes it easy to take along even when space is at a premium.
Field-Maintainable: Can be cleaned repeatedly for flow recovery without tools.
Super Convenient: Quick-Connect bottle adapter lets you filter water directly into a variety of containers, including all MSR® hydration products and Nalgene® bottles.

Mine has been great so far. MSR sent me a free cartridge just in case I had one of the defective ones.

You may already know this but you can get a gravity adaptor for the hyperflow.
