I bought this set on sale.  It's the first time I have had stainless steel cookwear.  I am following the directions with low to medium heat (never high).  I am scared to ruin them.  By following the directions; adding a few drops of dishsoap and soak while cooling down, they seem easy to clean.  Some times there is a milky look in the surface but I know they are clean.
I have not noticed my food tasting any different that with my old cookwear.  
I still love them though.
