I drink all sorts of tea everyday, so kettle is a necessity. I like this one for its sleek looking; seamless inner steel; quick heating, auto-shutoff, cool to touch outside, and keep 
water warm. It keep water warm, but since it has an opening on top, so won’t maintain the temperature as well as thermos. To me it is a little bigger than I prefer because I got small place and it is too heavy for me to lift by one hand if it is filled to max. I should’ve checked the size more carefully before buying it.
