Great product for price
Did a 1 night back packing trip at a lake in Colorado. Worked well and drips faster than a Sawyer from my experience. Easy to back flush - just blow the straw.
Buy this now, save water filtering time later.
"you have to send me the link for that" that is what my friend what has been backpacking many times before said to me. This was easily one of the best purchases of the trip since it saved TONS OF TIME gathering and filtering water. Full the bag to the 1.5 gallon mark, attach the line attach the filter and fill your water container! It's that easy. I would definitely buy this again, without a second thought.
