Familiarity: I've put it through the wringer
If have used an older type of Katadyn Hiker filter for about 5 or 6 years. very happy with it. Then the handle broke down - worn out apparently. Since I loved the pump, I bought a new one. During my second trip, after about 10 days of use, the plastic handle broke down. I could still use the pump by pulling and pushing the broken handle ... not very comfortable. And two days later, the connection piece at the bottom of the pump broke down. Bad quality plastic.
Since there is no better & cheaper & lighter pump on the market, I'll by a new one. But Katadyn should improve the strenght of the material.
