I should have listened to the bad reviews. I 'treated' myself to this kettle since I've been getting into tea lately, but what a mistake. After boiling, the once clean water has a chemical film on top, and smells of petroleum. I'm guessing it comes from the rubbery seal in between the metal heating element and the glass. I thought the smell and film would go away with time, or that maybe it was just impurities in my water, but no luck.To test, I boiled water in this kettle and in an old stainless steel pot I have (stovetop). When done, the Capresso water had nasty film and odor. The stovetop water was crystal clear.Kettle looks great! Too bad the water it boils turns foul and smells like poison.I took it back... searching for a new kettle now.
