Works well but if you install it yourself wear a glove to push the old unit out.  The thin metal springy tabs used to seat the unit against a rubber gasket  ripped a 1" gash in my hand when I pushed the old one out.  The gasket sticks so force is needed to move the unit and it gives all at once with your hand hitting one of the many very sharp tabs.
