Had sawyer mini for years, got over scooping water and squirting into bladders. Have been running the MSR trailshot for two years and I’m done with it - it’s nice for filling a bladder and sucks some thin water as a hybrid pump, but damn is it fussy with priming. I’ve had multiple backpacking trips where the thing seems to lock up and won’t prime, which isn’t a hard concept, and I’ve reviewed the little tricks MSR says to do. Love the “shake” backwash. So done.
Looking at putting a Be Free on my 3L hydropak seeker, or Steripen. I always carry tabs for camp water or aqua Mira.
