The K2S Kettle was superb, well-built and solid with years of service life and when it finally failed it seemed a good idea to find another, but times had changed and the new kettles all seem to come from China and have the same cordless base and the same basic design.
So look for another Russell Hobbs corded kettle and find it is not the same. In the old days Russell Hobbs belonged to Tube Investments, then ended up with Polly Peck and later under Salton with the acquisition of Pifco together with Haden and Carmen.
So it is just another brand name and another derivative product.....the kettle is not as solid as in the past and the inane concept of a water gauge is just another point for water to leak. So far the mains powe cord has had to be replaced, the little plastic plug being far weaker than on the K2S; and now the handle has started to separate from the vessel and water leaks from the front.
All in all not what it was. Seems you should buy cheap kettles nowadays and have the Chinese build a new one every two years for replacement. They wanted to make kettles a fashion item, looks like planned obsolescence is physical and not just aesthetic.
