The positive image of high quality that I associate with Brown, yet dates back to the time when the company was a German group. For several years I notice a drop in quality (for example, even when the Iron). The Braun WK 500 but sets everything to the extreme. The device looks - compared to the previous two years ago - very cheap, so hush-hush in China zusammengestoppelt. At first it smelled strongly of cooking plastic. After 2 days it started to use very loud - to whistle like a siren. After about a week using I meant first traces of lime on the heating plate to see. In fact - as I noticed shortly afterwards - the silver coating had dissolved on the hotplate to a third and a white layer was emerged. If you stroked the white layer, the fingers were white. In of such contaminated water I let a week pull my tea and my cooked soups. I am very disappointed that such defective devices - probably saves in quality control - come on the market and buy certainly never brown.
