Brian S.wrote a review of Katadyn Vario Dual Technology MicroFilter on April 2, 2013
Familiarity: I've used it several times
I like the filter. It's a little heavy, I kind of wish I got the Hiker Pro. I say that because its a little lighter and shares the filter with the base camp filter. But I also read about the handle breaking on the Hiker Pro and this one is much sturdier
I do like how it connects to my wide mouth nalgene bottles. It's like holding one thing instead of trying to pump and hold a bottle too.
My cousin and I both have this one. And both of ours leak a little when you push too hard. It's not that big of a deal because it is leaking before the filtering happens. The solution is to just not press so hard.
