Title: FATAL DESING FLAW -- DON'T BUY IT
Review: Do not buy this filter. The small inlet spout on the bottom of the filter breaks off with the slightest tap. We purchased the Katadyn Pro for a trip to the BWCA and after three days of use this part broke off. We tried super glueing it back but were unable to get a perfect seal and thus had only minimal pump quality after that. Upon returning, talked to the people at REI and learned that our experience with the pump was fairly common. So, we upgraded to an MSR ceramic. Wrote to Katadyn about the problem but have yet to get a response.
