Bought this about 6 years ago. Gets used infrequently (the weather in the UK...) and lives outside, with no cover. There is absolutely no rust on or in the kettle, and the grill comes up sparkling each and every time. It’s not even particularly expensive!
Recently found my parents 30+ year old Weber kettle in the back of one of their outbuildings, and it cleaned up almost as good as new....I have not doubts this will last as long. Thoroughly impressed with it’s durability.
