Nicholas ★★★★★

Used it on a long weekend hike and filled from a muddy stream, water came out clear and tasted fine. The filter is quick enough that I don’t hate stopping to refill.

Eli ★★★★★

Set it up in about thirty seconds on my usual hiking bottle, and the flow rate is way faster than I expected for something this small. Took a sip from a questionable creek and it came out tasting clean, zero hassle.

Penelope G. ★★★★★

Filled it from a muddy stream on my last hike and the water came out tasting completely clean—no weird aftertaste at all. Screwing it into my wide-mouth bottle took about ten seconds, and I didn’t have to squeeze or wait around for it to work.
