Product review (5 stars): Quality replacement part.
This replacement part fit our refrigerator perfectly.  We first thought our water supply line had a pinhole in it creating the annoying leak.  Upon further investigation, it was this part that was failing (well, not THIS one, the original one installed in the fridge).

This is a good quality replacement part.  It came quickly, and my ice maker was once again operational just in time to make all the ice needed to fuel my margarita machine for a Saturday afternoon pool party!
