Product review (4 stars): Works as intended
I have an Eterna GE refrigerator and have had a hard time finding any box store that carried this particular filter.  A quick search on Amazon found the filter I needed.  The filter twists into position and sealed first time no problem.  I can see how people could try to over tighten and break something.  It is really a half or quater turn to be tight and seal.  I didn't have to shut off the water before installing and it seemed to work fine.  I guess if your ice maker called for water while you were trying to replace the filter you might get a mess or maybe a valve closes when the filter is removed??  Either way no need to shut off the water and the instructions don't indicate you need to either.  I added water to the filter before installation per instruction but still had a lot of noise from air in the lines.  It took a couple of days but the system is quiet now with no rattling from air in the lines.  The water tastes filtered and it removed the smell that had started with a filter that was probably 4 years old.

We have a sink RO system and the water tastes much better with ice now that we have replaced the filter.  We often drink it without ice but with summer on the way I'd imagine the water temperature will be less appealing and require more ice.

Overall a great purchase but wish plastic and carbon was cheaper!
