Bought this product and yes, it heats up water. However, the heating device on the bottom of the kettle emits a rusting by-product every time i boil water. I've given it a chance....had it a month now hoping it will stop. It hasn't. This rusty by-product has even stained the inner walls of the kettle. In addition to this, which should be enough not to buy it, this kettle was designed with no on/off switch and it is annoying to have to unplug the device to turn it off.
