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.
