My Nan had a whistling kettle when I was a little girl and I don't know why I've waited so long to buy my own.
The kettle itself is pretty basic. Large, sturdy and capacity to hold lots of water. The high gloss surface can be a bit of a magnet for sticky finger prints however and I guess it's not the kind of kettle you would buy if you want a quick cup of coffee before you rush out of the door to work, it's rather slow. If this isn't an issue for you however, then I really can't fault it.
I love hearing the whistle sound signalling tea time whilst out in the garden. My cats however are less impressed and it's up there with the hoover in the 'scary noise' stakes.
