Great for everyday use
Love this because I can pre mix water with electrolytes and start my hike and not ruin the filter and just pop it out and filter lake or river water right after and I like to carry my grayl now as just a heavy water bottle on my tool box so no matter what my grayl never leaves me

Did not get a brand new item

C**.
Does not work with the Geopress
This is only the valve for the ultra press does not work with the geo press.
O**.
Prevents possible Cross contamination when adding electrolytes to the fresh H2o cylinder
Easy installation a recommended. Product . . A reminder is to Remember like all h2o water bottles remember to clean the fresh water holding cylinder to prevent Bacteria up and let the filter area dry out occasionally .
