Product review (5 stars): 3rd filter purchase, and works as well as the rest we have received.
Prices seem to keep dropping.  Filter arrived quickly.  Installation was simply push-in for our GE side by side fridge with bottom freezer drawer.  Some initial leaking because I pulled it out and pushed it in again to make sure I had it inserted correctly.  No leaking at all now.  If you do get leakage, someone recommended trying newer o-rings from the hardware store.  I would try new rings first before returning the filter.  You have to siphon at least a gallon of water to get rid of filter particles and air in the line but then water runs clear.  Two gallons recommended but one gallon worked for me.  Normally, our tap water tastes fine to me, and with this filter I didn't notice much difference in taste.  We used the fridge water without a filter while waiting for the first one to arrive and really, it is the same as the tap water.  So, if filtered water helps you sleep at night, I would go for this deal before spending twice as much for the alternative.
