I have had this kettle for 2 years and it is now starting to smell of 'BO' - I was told this is break down of the plastic.  The rim around the top is breaking down so this must be where the smell comes from. The kettle does not switch off immediately it has boiled so fills my kitchen with steam, I have even tried to hold the lid firmly down but it does make any difference.  I bought this to replace a Russell Hobbs kettle and it has not been as good.
