I originally bought another brand that did not have the features that this one does.  Was not happy with it so I found out about this one and after buying it I find that there was a world of different between the two.  No more burnt mouth from too hot a water for my tea.  I also love how fast it works.  Now I can make hummingbird food in half the time because of the boil feature on it.  Would not buy anything else.
