Have any of you used this type of water filter before? I first saw a very similar product at the ISE, but didn't buy one. I know Katadyn makes one that is similar, but you have to suck the water out from what I understand. This one allows you to squeeze the bottle. It's very light weight, don't remember the exact weight, but definitely lighter than my Hiker pro. Plus it eliminates the need for a regular water bottle. Just wondering if anyone has any info on them.
They are pretty cool for day hikes but not really practical for backpacking. As you can only get 22oz or so at a time. Also the one I had you had to squeeze pretty hard to get the water to come out which was a pain.
