Product review (1 stars): It's worth paying extra for the original part
This is an "after-market" product that costs about 1/3 less than the original name-brand replacement.  When I received it, it seemed as if it could possibly be used.  I suspected this b/c the label affixed to the filter had sort of "stretch" tears on it (the kind of tear from a twisting motion that might occur from torquing the product in or out).  Besides that, there is a seal that goes on the very top which was present but not affixed, and the box seemed a bit dirty/smudged.  I put the filter in after following the directions of filling it with water, etc., and I immediately noticed a strange taste in the water.  I thought maybe I just needed to run it for a while, but the taste never went away.  I kept it in for several weeks but both the water and the ice tasted weird.  I contacted the company & they assured me it was brand new and offered to refund my money.  I returned it to them & got a prompt refund, which was great (they were very responsive & pleasant to deal with). Then I purchased the name-brand part & the water tasted normal again (after running about a gallon through).  I'm going to stick to the name-brand original part from now on.
