I think I've found a use for this thing every single day since it arrived.
When I opened it, I followed the manufacturer's directions and boiled 3 full pots of water before use. At the end of the 3rd pot I looked inside and saw a bit of film in the pot, which I expected. I had no problems cleaning: I used my
bottle brush to get inside and into the corners since the handle doesn't swing out of the way. (I don't have babies in the house, but the bottle brush is great for water bottles, vases, and all sorts of other grownup items.)
A few of my uses I've timed its performance. I can hear that water is boiling in a full pot after only 90 seconds. Color me impressed! When I'm using it for tea, I don't let it heat much past when I hear the water start to boil otherwise it'll be far too hot to drink. A few days later I timed how long it took for the automatic shut-off to flip, which was just under 7 minutes. When left on the dock, the kettle seems to keep warm for quite a while. Either that's a feature, or the kettle is just amazing at retaining its heat. I don't recall offhand if I read that in the manual.
I haven't seen any film or sediment since the first "cleaning" boils. I have been using distilled water since my home drinking water is distilled. I'm sure it helps reduce the frequency of required cleanings, and it definitely ensures my water doesn't "taste" like anything. Good water in --> Good water out.
The image on Amazon makes it look like there's vertical stripes on the metal housing, which there are not. It's a sleek dome shape.
A "full" pot is 1.7 liters, 57 ounces, just over 7 cups, just under ˝ gallon, although the fill indicator only reads in liters.
So far I've used my electric kettle for the expected tea and hot chocolate. I've also used it for dry soup mix and to speed up pasta cooking since my cooktop takes ages to heat water to a boil. I've been recommending this product to everyone. I'm not sure how I got along without it before!
