Product review (3 stars): Keeps Popping Out -- Doesn't Work--UPDATE: Now Works
UPDATE:  I finally got the filter to click into place. It takes a healthy push--I mean hard!  Once I got it into place, I drained off about a gallon of water. The water now TASTES GREAT. We even did a blind test with our favorite bottled waters. SO WHY JUST THREE STARS?  The cost is ridiculously high.

ORIGINAL:  Filter is way too expensive, but more important the filter keeps popping out.  I put the old filter in and out without a problem.  This filter appears to be a little longer than the original -- I think that's what is causing the problem.  Not happy -- I'm returning this tomorrow.
