I have the typical 1.5 litre whistling kettle but would like to find one that actually pours properly.
Any suggestions from its hand experience.

I have the same kettle and was also not happy with the way it pours.
Aldi had Adventuridge 2.5 ltr whistle kettles a couple of weeks ago and there were a few left at Arana Hills QLD Aldi, I decided to pick one up today cost $12.99, much better kettle, pours well.
The new kettle tales the same space as the old one thanks to the folding handle.
