Product review (1 stars): Be careful with water filters that are inside the fridge!
Be careful! One of these filters I bought was defective and leaked.  But because it is mounted in the back of the fridge, we did not discover it was leaking until after the water leaked into the vents between the freezer and fridge compartments and froze.  It took a couple days to defrost the whole fridge and melt out all the water.
