I’m much prefer having this instead of the syringe that comes with the Sawyer filter. I use this to set up a gravity filter and to back flush my Sawyer filter I would definitely buy it again. It makes filtering so much more convenient.

Beautiful and quality product. I advise.

I can't believe something so simple it's a life-changing when you're on the trail. I partner this up with my Sawyer water filter, my Conoc bag, and my smart water bottle and it makes for an incredibly easy filter setup and I can even use this with my smart water bottle to back flush my Sawyer water filter.

This is a must for to gravity feed from a CNOC to a Sawyer filter and then to a smart water bottle. Keep the connection loose from the smart water bottle to the Sawyer to keep the flow steady.

Reviews are relative to each individual's experiences. I'm not an expert, but I do have a lot of backcountry hiking experience, and this product is a must have for an easy, hands free water filtration system in the backcountry.My system is like this:CNOC 2L bag for lake waterSawyer SqueezeSawyer CouplingSmart Water Bottle (or any 28mm bottle)Attach everything in that order, hang your water bag on a try and let gravity do the rest.This hands free setup lets me do other things like setup my tent or eat while my water is filtering. I forget this at home one time and I was so annoyed having to hold the water bag while trying to line it up to the water.I'll never leave home without it again!
