My refrigerator is continually "burning-in." It amazes me that veggies continue to be crisper, the glass shelves have more transparency, white wine stays fresher longer and the volume of the interior seems to be getting larger. Hard to believe but it is true. I can see, smell, taste and feel the differences. Unfortunately I cannot hear a difference. Bet if I tried harder I could.
Burning-in!! The critical element in achieving maximum product performance!
