I am extremely disappointed with the burnished beater.  Cake batter turned a frightening gray while creaming butter and sugar.  This beater was the replacement for two (2) coated beaters.  I thought this new type would be a good replacement - guess I as really wrong!  Why not make a plain stainless steel beater. I love my mixer..... No point having equipment without a serviceable attachment.  Sad in K-town:(
