Product review (5 stars): but I love being able to order it and have it delivered ...
Fits our refrigerator perfectly.  I haven't really done much price comparison, but I love being able to order it and have it delivered because I never seem to remember to pick one up while I am out and will end up with the "replace filter" light being on forever if I don't just go ahead and order it online.  It does seem to be a reasonable price from what I can tell, and the water that we get from it tastes great.
