Product review (1 stars): can no longer read my oven knobs!
I have a Viking cooktop and wall ovens, which were installed in Dec.  2007. Luckily we haven't (yet) had problems with the actual cooking functions. However, the black paint identifying the burners on the cooktop has worn off. Luckily, a white "ghost image" remains.  Unfortunately, the letters on my oven, identifying knobs and temperature readings, have almost completely worn off in places.  The steam appears to make it worse. the 400 has disappeared from each knob. It is easy to scrape it off with minimal effort.  And once it's gone, it's gone! No "ghost image"- nothing. We bought these appliances because they were supposed to be so great. What a ripoff! Buyer beware!
