It' fast, easy to use, inexpensive and shuts off when it boils. I've given at least 8 as gifts and just received 3 more  to take to my grandson's wedding to give to him and 2 other married grandchildren.  
I received my first one as a gift three years ago and it's still going strong.  I'm 79 and love the convenience and that I don't need to worry about forgetting a kettle on the stove. Some folks I've given them to even want one for work.  The best gift ever!
