It'll boil a liter and a half of water in about 5 minutes, and it's about as hard to use as a toaster. Fill with water, press lever, walk away. No need to worry about dry-boiling a pot to death, or enjoying a house fire with your Earl Grey, or having the base melt a new circle into an old sideboard.
In short, it's fun, convenient, and worth the money. My only peccadillo is that you get boiling water, and that's it - you can't set the temperature, so no fine-tuning tea without a bit of experimentation first. But, if you're that worried about having just the right temperature for your dragon pearls or hibiscus petals, you're probably not using an electric kettle, either. For your Lipton or your PG Tips, this rocks.
