Product review (4 stars): Seems Fine, But Not Clear If Installed Properly..
It is difficult to judge whether the filter works as well as the GE GSWF.  The ice cubes taste the same.  It fits the space properly. How else can you tell?.

One comment that I can judge:  It would be nice if it was clearer as to when it is fully installed.  The GE version ends up with the turn 'handle' (really just an extrusion at the bottom of the filter) fully horizontal, with the arrows pointing each way to install or remove the filter.  This version just kind of went in and the handle/extrusion ended up sort of sideways, kind of pointing at 11:00 and 5:00.  So it's hard to be sure that it's installed properly.  This would seem to be an easy improvement, but I guess the make of the product didn't realize that this feature is a plus.
