The kettle has accompanied us three weeks by England and supplied every day with boiling water for coffee, soups and hot water. The boiling of 1L takes about 15 min., Which too verkraft well during highway driving and 12 V is understandable. The unit worked flawlessly. The base heats up not very strengthens, so we put it in the accounts center armrest. An on / off switch and is present, the cable is long enough and the shell is stable, so that it does not deform. The lid can be opened for cleaning. The investment has paid off. I would buy the kettle at any time.
