I use this product daily. I have had it for a little over 6 months now with no issues! I recommend using the smallest burner and boiling slowly. Be very gentle with it as the glass is fragile. When cleaning it, if using a dishwasher, put it on the top rack for the best results. It is stain resistant as well. It looks the same as when I first bought it! I would highly recommend this kettle to a friend. I really only think it's good for in-home usage unless of course your place of employment has a stove, and if that's the case, then I say go for it. I bree coffee daily for myself and it still runs like it's right off the shelf from the store!
