We have had our glass kettle for 6+ years and it is still going strong,and looks as new as the day we purchased it.We are on permanent rain water,so that helps as mains water is full of chemicals and minerals that eat away at any material.The workings of this particular kettlenare very strong and of good quality.Webwill definately buy the same kettle if this one ever gives up the ghost.Keep up the good work Breville
