Review on Enhance Your Deuter Streamer with Helix Valve Replacement Kit by Joseph Scalea

Replaced the valve on a 3 liter water bottle, then filled it up completely for a long day hike. No leaks, even when changing altitude with the valve closed. Only two small issues with the design of the valve: 1) The old valve had to be cut off, reducing the length of the line. While this is actually reasonable, it would be nice to know as I would order a new line to avoid losing length. 2) The mouthpiece needs to be twisted to fully protect it from leaking. This makes it difficult to use when I'm cycling instead of hiking. A push-pull valve would be the best solution for bikers. Overall, the product works as expected.
