Product review (5 stars): Works great, with no bad taste.
I used this for a new install of an icemaker in my house.  I flushed prior to hookup, and have not noticed any bad odor or taste in our ice.  I did throw out the first three or four full trays of ice, and it has tasted great since.  No leaks, no tape or putty required, just hook it up.  I was very concerned about taste issues, that's why I went with pex.  As usual, it didn't disappoint.
