3 stars because of the expense.  It is impossible to understand why they charge so much other than because it is LG.  If the knobs were engineered better, we wouldn't have to replace them in the first place.  Kind of ridicules considering the $2K price tag that came with the oven just four years ago.  I have one more that needs to be replaced, but I am holding off to make sure this one stands the test of time first.
