Product review (1 stars): but it still tastes horrible. My wife refuses to drink it
Installed one filter from a recently purchased  4-pack.  It had a funky taste, but I assumed it probably had not had enough initial water run through it.  Gave it two weeks (and lots of flavored drink mix), but it still tastes horrible.  My wife refuses to drink it, and now uses our old britta pitcher.  Unfortunately I missed the return window by one day.  I hope it is defective because I have had success with similar filters from amazon in the past.  At 40+ dollars it looks like the better deal would have been the OEM after all.
