Highly recommend, did its job perfectly!

Went on a three day backpacking trip. The lake was frozen over but one of my friends managed to crack it open. I just dipped the bag and brought it up and we filled a 5 gallon bucket with a couple trips. Everyone loved this. It was very easy compared to some of the other ones others had. I would highly recommend this And it’s versatile too.

Must have for backpackers.

Does exactly what it's supposed to do. Gives you clean drinking water with multiple ways to use it, like a straw, with a bottle(bag thing) or a 1.5 gallon bag that you can hang and let gravity do the work so you can enjoy camp rather than squeezing a bottle for 5 minutes every time you need water.

Best new addition to my camping gear.

Pros1) next best thing to having a portable tap in the forest.2) Gravity fed purification process is much better than squeezing a plastic bag.3) holds a sizeable amount of water which reduces trips to the river.4) compact and lightweight when hiking. Especially given the functionality it brings.5) feels very durable and works well no hiccups so far.Cons1) if the river is low on water involves a bit of strategy to get water in the bag.2) the tap on the hose squeezes the hose itself it’s not an issue now but it may lead to a leaks after many uses.In summary.Very happy with this purchase this is going to be a mandatory item on any hike I go on in future.

Covers all the bases

This is a very versatile water filter system. There are many options available to use it. I used it to filter some water from a trough I fill for deer to drink from. I have a game cam placed to watch what drinks from the trough. I had some pictures of a raccoon taking a dip in in too. Took a little nerve but I went out and got a cup of water from it and ran it thru the filter. Gulp. But it tasted just like normal water and that was a week ago and am still doing fine. I can personally attest to the ability of this filter to purify waters

Loved it. Lightweight and packable. Easy to use

Bought this last year for our 10 day pack trip into the Bob Marshall wilderness. We all loved it. Noone got sick. We got water from the river. Easy to use and pack. Lightweight. Using it again for the same trip this year.

You get what you pay for

I'm not very happy with this purchase. Sure, it's cheaper than most gravity filters, but there are some drawbacks.The filter/straw does not provide a way to connect and drain into either a hose or a water bottle. You have to hold it. In other words, if you want to hang the whole contraption from a tree, you have the dirty resevoir connected to the hose, connected to the filter, connected to nothing. If you wanted a resevoir for clean water, you would have to stand there and fill the container.Second issue: the hose connects to other pieces (up and down stream) using pressure fittings, and the pieces will eventually slide off. If you hang the whole contraption, you have gravity actively pulling the filter off the hose. Not ideal.Beyond these issues, the filter works as expected. You can screw only the filter onto the provided water bottle and suck/drink directly. That's neat, and I wish they provided similar screw fittings for other parts of the setup.
