Follow up -- Well Katadyn has terrible service. They were to ship me a pump when their backorder came in. That turned out to be untue. I waited two months, spoke with them 3 times and they finally told me that the pump has been redesigned and that it will not fit the hose on my stove. Thanks. I have a leaky stove that is useless. Campsaver is where I bought it and they directed me to deal directly with Katadyn. When I called them and told them the situation they told me they would have to charge a restocking fee of 50% because I was past my 60 days to return. It was their idea to try and deal with Katadyn, otherwise I could have returned it when it was only two weeks old. I feel like a sap. Well anyways now I have to find a new stove and I am out 117 dollars. This time I will pay much closer attention to the reviews, and I will certainly use a store with a better reputation this time, like Campmor or REI. This is my first bad internet purchase experience and I hope it is my last. Buyer Beware.
