Hi natterjak
Yes, your experiences are similar to mine. Last 2 kettles we have had have been from what one would think to be reasonable makes and at a price where you would think they would last for several years. But like you, they last less than 2 years. Usually for some silly reason like a small piece of plastic that keeps the lid shut snaps off.
Plus - they do not want you to repair them. In most cases you would not be able to get spares. They want you to be forced to buy this stupid 3 year extra guarantees and or just buy a new one and fill up landfill sites with busted kettles....
