The product: Siemens Porsche cordless TW91100 kettle (right). The puff: 'You don't have to blow the budget to show your partner how much you love them. Forget breakfast in bed! Whatever the occasion, if you want to impress, simply treat them to breakfast in a 'Porsche'.' The look: Brushed stainless steel with black trim - iceberg meets stormtrooper. Wow factor: The manufacturer says that it works just as well with tea or coffee, which is like promoting a shirt you can wear indoors and out. A more impressive boast is that the stainless-steel scale filter in the spout 'provides the right water quality to make your cup of tea taste the way it should'. The quantity can be viewed via the water-level indicator with prism effect. Another innovative detail is the cool-touch insulation, which means that, despite being metal, the outside should never burn your fingers the way old-fashioned kettles did. The damage: About $1,000. The product: Braun WK300 AquaExpress cordless kettle. The puff: 'Combines unique design with rapid boiling for the ultimate performance. Boiling water has never been so fast, easy and safe, and it never had such a stylish touch.' Wow factor: Said to be the fastest kettle on the planet, the Aqua-Express takes less than a minute to boil 250ml of water. It's a dream for the un-co-ordinated or those prone to drink harder stuff than tea. It has a non-slip handle and a swivel base, which means you don't have to be accurate when you replace the kettle - it flops into place. But condensation can build up on top of the lid. Water can also gather at the base, potentially resulting in a short circuit. The impressive speed comes at the expense of noise - a no-no in the era of cool'n'quiet technology. The damage: About $450.
