wait for them to replace the injection mold to be cost effective.

None of the other filters I own, including the SWA have any provisions for
such a test. I guess I just know it is under almost no pressure and is
really unlikely to leak. At least no more than any other filter. It is
unfortunate that it's made out of plastic, there for delicate, but I can't
think of any other way they could make it better. I think the fact you can
replace the filter is part of the problem. The savings for us is minimal and
probably not worth the trouble of disassembly and reassembly. They might
want to conceder just sending the filter pre-assembled and not offer a

with the first units. I was just as interested in seeing if and how they
would respond as I was to test the gear.
All of the testers that received filters should send in reports on how it is
going with them even if it is just playing with it around the house. The
only thing I can offer manufacturers for their gear is the promise of posts
on the list of good and bad things about their new products and exposure of
those products to a very select group of experienced backpackers. We can't
know what is going on with each of the products if we see no posts. By the
way, by "we" I of course mean the people on this list.
