It was super easy to set up and start using. After a couple of minutes, you're ready to go.
It doesn't hold a lot of water, but it's absolutely fine for two mugs full, and because of this, it takes no time at all to boil. 
It has a lovely blue glow when you click it on (courtesy of the little lights inside of the water tank) and it's surprisingly quiet when in use - much quieter than previous kettles I've  had. 
It comes with a Brita filter to start you off, which says it lasts approx 4 weeks with regular use. I won't use it every day, so it'll probably mean that one filter will last a bit longer, but only time will tell. 
All in all, it's a sleek looking kettle that filters and makes a nice drink.
