This is a great refrigerator from LG.  It has the ability to self diagnose any problems and can be software updated via online access.  Tap the glass twice and the light turns on so you don't have to stand there with the door open.  Craft Ice is a great option when it works correctly.  I had to have mine replaced under warranty because it stopped working correctly and was filling the bin with water instead or ejecting the ice.  That is the reason for 4 stars otherwise it would have been 5 stars.
