Product review (3 stars): Leaks just like the old one did, even better.
I don't know why but this one leaked for almost a month.  Just before I was completely fed up, it quit leaking.  Yes I ran gallons, upon gallons of water through it.  Not sure how or why it quit leaking, it might be that the fridge is the problem.  In any case, we've had it for a couple of months now and no more leaks.  Admittedly the old style filter leaked for a day or two, but for a whole month.  Come on Whirlpool engineers, do better.
