Query: Braun WK200B

When we received this product and plugged it in it made a terrible sound for the first week. It was so bad we contacted the manufacturer, and learned they had discontinued making the item. They offer us a refund if we returned the item. After a few weeks the noise stopped and the kettle has been fine. This is the second kettle we have bought with the first one lasting about 4 years before a bad design element caused it to fail.
