Product review (3 stars): Appear OK, Performance not determined yet.
Received these promptly, and they appear fine, but I haven't installed one yet, so performance is still an open issue.  Oddly, they came in bubble-wrap bags and not cartons as shown in the web page image.  Makes them more difficult to store upright on a shelf, but otherwise ok.  I'll update this after I actually install one in the Refrigerator once the OEM one needs replacement.
