Product review (1 stars): DID NOT REPLACE GSWF.
Tried to install but would not completely turn to seat and leaked.  After many tries,, resorted in purchase of the GE filter. Comparing the two revealed small tabs on the GE filter. (To allow the filter to complete turn and to seat?)  Also,, the center recess was too large and would not seal at the o-rings at the filter shaft in the fridge. cannot use. still have it.  Very depressed.  Gave it a 1 star as did not see a lower amount.
