Product review (5 stars): Works fine.
Having installed this filter before on my GE, I was surprised this time that it did not twist on as in the passed.  However, it proved not to be the fault of the filter, but the gasket for the old.  As I discovered, the o-ring gasket from the previous filter has stuck to the frig and this prevented the new filter from attaching as normal.  Once the old gasket was removed (it sort of fell off the fitting), installation of the new filter went fine.
