Why do my French press guts always break?

[Rolando]

I use a cheap Frensh Press from Ikea. Glass pot, metal filters, comes apart for washing.

I broke one when I dropped it in my ceramic covered iron sink. Bought another.

EDIT: I re-read your post. Maybe its metal fatigue? Are you pouring boiling water in cold press? Are you rinsing a hot press with cold water? That COULD POSSIBLY cause the welds too fail...
