I have had the unit for a few days and it works fine. BUT, the labels on the knobs are light gray on a silver background and I need a flashlight to read them, even though the kitchen is well lit.  The letters are on the edge of the knob and you have to be just above the knob to see them, and, even then, have to twirl the knob to catch the lettering in just the right way.  I am asking LG to send me better knobs if they have them.
