I didn't realize I needed this until I used it for the first time.. I use it for all the different teas that we drink and I'm just beyond impressed!! The heat settings for each type are perfect.. I didn't even know I needed that either.. the taste of my different types after using the proper setting and temp have made a HUGE difference. It boils very quickly ..keeps temp for a long period of time even after it's off..and now I have to mention how beautiful it is on my counter!! The stainless steel is beautiful and the design is perfect for any style kitchen.. I have removed my coffee pot and will never use anything else for coffee or tea again.. totally worth it.. beyond pleased and highly recommend it!!
