After some initial testing here are my first thoughts of the Takahiro..
It's magnificent!
The reality is that I don't have any way to compare it to other thin spout pouring kettles but I can compare it to standard electric kettles like the Melita, Aroma, and the standard kettles available in stores.
No comparison whatsoever.
I think now that any kettle that gives you very fine control is worth seeking out should you be pourover inclined. I've got loads and loads of pours to make before I have a handle on exactly what I want to do with it but water control at this level produces immediately noticeable differences in depth of the cup and extraction smoothness.
Without ever holding another thin spout kettle in my hand I can't say how one stacks up against the other I can only say the Takahiro offers plenty of size, an attractive look, very nice balance / feel, and for me unprecedented control. It's very sturdy and I totally dig it.
