We got two of these for a recent trip and are so glad we did, didn't get sick at all during our 2 week excursion. They are simple to use, pack well, and I love that you can squeeze the water out through the filter - you can also suck like a straw but the squeeze is for if you want to filter water to mix into something else.I would recommend filling the water bottle and squeezing water through the filter at least 3 times before first use. The filter has a very distinct and not great taste at first but that goes away after a few rounds of water through it.

Works as intended. So far no ill effects from multiple uses. Backwash syringe is a nice touch. Works well as a rugged squeeze Bag to fill other containers and once primed, filter flows and works great!4/5 o only because filter takes a large amount of space and a few ounces cannot be filtered and remain in bag.

Bought this for a hike up Mt Whitney. It was easy to fill from ponds, streams and springs, easy to squeeze to filter the water (either directly into my mouth or to fill my camelbak bladder) and since I didn’t get sick, I assume it did its job by providing me with clean, filtered water.Good price. Happy with this purchase.

Love it, used it all summer, good quality. I like that I can scoop up any water and drink it. Backwash filter is easy. I bought another for the lady.

We bought two of these for our camping trip in Costa Rica and they were perfect. When empty, they fit pretty much anywhere and when full, they also are very easily packable. At times it's a little hard to get water out, but once you get the hang of it, it becomes very easy.

Skickades tillbaks då den var trasig vid leverans. Det märktes att paketet var öppnat innan jag fick det. och korken måste ha varit åtdragen för hårt för gängorna hade spräckt plasten vid flaskhalsen. Att den dessutom var tidigare använd och inte ny i förpackning gjorde mig besviken.

Simple to use as a filter & drinking vessel. Only used from mountain springs & stream but tastes fine & I'm still alive!

Muy ligera y practica. Recomiendo para travesías o senderismo en montaña sin tener que cargar 3l de agua.

Do not believe the advertising images, where you see absolutely transparent water on the way out. I just returned from a two-week bike trip through the deep forests of Quebec and have used this product several times. Wherever I got my water, lake or river, the water was still dirty and yellow after filtering. The water tasted the same, both before and after filtration. Fortunately, I was able to draw water from natural springs, but it is terrible when such a product, on which sometimes a person's life may depend, is sold in such terrible quality.
