Definitely a thumbs-up on a single cup pour. Unfortunately there are two of us in the household.
I would probably give the larger kettle a thumbs up but I don't know if I'm willing to drop 200 bucks on it.
I will admit the controllability of the pour is unparalleled to anything I have had in my hands. I usually do a 24 ounce pour with the breakfast and another 24 ounce pour for our go cups on the way out the door. With 24+ ounces of liquid in the kettle, at max temp, water would spittle out the spout completely negating the wonderful pouring ability the spout allows. If I lived alone, this kettle would probably be on my wish list right now. Then again, if I lived alone, I would have a lot more money to spend on coffee gear.
