Dezin electric kettle:"The best."
We drink instant coffee everyday and use this to boil water multiple times per day for the last one or two years. It works perfectly and reliably. We fill it with RO (reverse osmosis) water and it's never needed cleaning and has never developed any discoloration or spots or anything. It still looks like the day we got it. It automatically turns off when the water reaches a full boil. It holds a pretty good volume of water. I will happily buy this again if this one ever dies.
