My other filter is a Platypus Cleanstream grafted into a ULA Amigo Pro's hose. I can drop my backpack on granite with the filter on the bottom and it won't crack, break or otherwise become unusable.

I don't trust MSR filters not to crack or clog either - have watched too many people have to field strip them.

The Hiker Pro I have is suffering its age, there's a crack around the outlet hose housing. It's plastic. You just anticipate the end and buy them at REI....
