Very simple to use. Heats up fast. The outside stays cool, my kids can touch it with no issue. I’ve been using 175 for tea for myself and 160 for my kids tea. I like that it will shut off if no water is detected. No more burnt tea kettles because I get caught up in work, kids school or cooking. We’ve been using it more than I had anticipated.
