Product review (5 stars): Easy as can be
Easiest installation ever.  This is the first time we have had to replace the filter in our fridge.  The original filter lasted almost a year, which is great (in a household of 3.)  WAY cheaper than buying from GE directly, too.  So easy to replace, twist on and off.  With any luck, this replacement filter, which is the exact filter that was originally in our fridge, will last just as long.
