Bought the electric steraliser been using it for 3 weeks the instruction say to descale 14 days 21 days and 28 days I'm not happy with the product at all I am using it correctly using the correct amount of water each time emptying it after each use and the metal is disgusting I have to descale and clean it everyday after two uses as it is brown and have to scrape off the descale this should not be happening I'm using it correctly these are the results after cleaning and being used twice in 24 hours .
