Product review (3 stars): Will not fit in all MWF applications
I have a GE fridge ( model DSHF6VGBCCBB ) with a 'Smart Water Plus' that takes an MWF filter, but these did not fit.  I think the shoulders of the cylinder must be wider than the name brand GE filters, because I could just spin this one endlessly in the socket without the top part ever even touching anything, much less locking into place.  I'm sure it works fine in most MWF-style fridges, but just wanted to let people know that there are at least some where it doesn't.  BTW, Amazon was very quick to refund my money when I returned them.
