Product review (1 stars): I am very disappointed.
I would give a 0, if that was an option.  This was the second filter we purchased that will not lock in.  Trying to install it resulted in water all over our floor under our refrigerator.  It was a mess.  The old one clicked right in, so I know it's not us installing it wrong.  We compared them very closely to maker sure that we had not ordered the wrong one.  Identical!  We did not return the second filter in time, so now we are out the $$$.  I am not sure where Amazon is getting this filter, but it is a faulty product.  I am very disappointed.
