Input: I've now had mine for 1.5 months. Love that it saves me from buying paper filters so it has already paid itself off in a months time. Fits perfectly in my 8 cup Chemex coffee maker. Easy to wash. However, it did not hold its shape well, after a few washes (by hand) mine is all crinkly and doesn't look as pretty as when I got it, not the end of the world. Water filters through pretty fast so I don't feel my coffee is as strong tasting as it could be. And recently I've started noticing a metallic taste in my mouth and coffee - not sure how safe that can be. (Shrugs shoulders) Assuming not too good...
