FWIW, I had several Magimix kettles over many (c 20?), although I only paid for one because, despite being spendy things, they had a propensity to break as they were too complicated for their own good. While they were still being made, I found that the customer service would honour failures through manufacturing/design fault, which is why I never had to pay any more. That not being the case, when the last one died relatively recently I had to go shopping.
My wish list for a kettle looked like this:
- 3Kw element. Fast boil is useful quite frequently, there is no energy saving to be had, so why not?
- ideally 2 ltr but I discovered that's tough
- robust, with an unfussy circular cordless base. My experience of the Magimix suggested that the simpler the better, so temperature control seemed like a fault vector to me
- Cool wall was a nice feature of the Magimix, but I decided I could live without it
I ended up with this
