Product review (5 stars): buying this here was a smart move
I got the two pack. Filters arrived ahead of time in perfect condition.  Easy to install, just follow the three easy directions. Fill with water, line up arrows and screw a half turn.
 When my refrigerator filter light indicator turned yellow (warning), I could still use the old filter for about 1 1/2 months before the indicator turned red (time to change). This is like the printer cartridges that tell you it's time to change them when you still have plenty of ink left.
  Price was much cheaper than direct from GE.
