I tried many electric kettles before purchasing the ZWILLING Enfinigy Electric Kettle.  Others broke after 1 use, leaked, etc.  This is not the case with the ZWILLING Enfinigy kettle.  I like that the main kettle is all one seamless piece.  I feel as though this is a major component to ensure that the kettle does not leak.  I love this kettle and use it every day!
