This is the one to buy.
Our family has been using this electric kettle on average 2-3 times a day over the last 12 months and couldn't be happier. It consistently boils a full tank of water (about 1.5-1.7 Liters) in 5 minutes time versus around 19-20 minutes for a typical water kettle over a gas range. Surprisingly, we have noticed no decrease in the amount of time that it takes to boil a tank of water over that time period (even after upwards of 800 heating cycles). The brushed aluminum finish looks good on the counter and it is easy to clean (mouth is large enough to fit your hand in it). The auto off feature is a nice touch as is the little 'ding' that indicates that the kettle has finished its heating cycle. Overall we are very happy with this purchase and wholeheartedly recommend it to anyone.
