Product review (5 stars): Save $$--buy this filter
08/25/2015 Update:
I just bought my second one of these filters.  Installation was again super simple and it seems to work fine.  I don't know why anyone would pay so much more for the GE filter!

This filter is comparable to the GE one for a lot less money.  Installation was quick and easy--instructions were right in the side of the box.  They were pretty straightforward, except for step 1, which said to turn off the water source to the refrigerator.  Well, I didn't know how to do this without moving the frig, so I didn't do it and it didn't seem to matter at all.  Overall, I'm very happy with this purchase and I'll buy this filter again when needed.
