After 5 years, the cable in the base where it goes into the kettle was cut. I unscrewed it, all the plugs inside are crimped, you can't cut it and put it a little further inside, so it's going to be thrown away. The opening showed good quality construction with good insulation. For as long as it worked, it was good. The salts, because the drum was smooth in most parts, came out with a simple sponge wash.
