Product review (5 stars): Fantastic OEM replacement
After reading all of the reviews I purchased this WSG-1 for my GE refrigerator.  The MWF cartridge is standard replacement and I noticed some comments about leakage.  When I installed the filter, I did nothing special.  I simply unwrapped it and installed it and I have no leaks.  There are directions (easy to follow) for any of you who are concerned about this but, this is a viable alternative to the MWF that costs twice as much.  As for the review with the comments about the filter lacking standards... Dude, really?  It's 1/2 the price! and... The water I'm filtering is safe to drink before I filter it.  My interest in filtering is taste, the WSG accomplishes that so my coffee and water tastes fantastic!  I highly recommend this as an alternative to the MWF.
