An important aspect should be the capacity, 1 liter is not enough, for example, a whole pot to prepare tea, popular models with 1.7 l have as advantages. The Russel Hobbs here but has no minimum amount, because the heating element is not exposed. He has his strengths definitely for smaller amounts, ie up to three cups.
If the price, there is of course much cheaper models that ultimately get the water as hot, and does not need much with heating capacities to the 2000W longer or shorter. The price is justified firstly by the high-quality optics and processing and also by the possibility of cooking a single cup and the sophisticated total package for me but.
