For some time we spent in the kettle with adjustable temperature. Initially philips, but it made the soul after 1 year and a half, the guarantee market but rebelotte 1 year and a half! So we changed brand for Riviera and Bar, silent, stainless steel, it looked good, but we have not managed to do from the plastic taste! Every morning the had a bad taste of plastic, a horror. So seeing the reviews we thought at least this one level plastic ca will get better. So actually, it fulfilled its role, we drink our tea without back taste, temperature rated, programming the temperature remains in memory instead of the two that we had previously. And finally, it's very nice to see the water boil in the kettle! In short the least expensive of the three final we had and so far the best, to see the longevity now.
