Input:
This seems to be a great product, but it does not last more than a few months. I have had 2x of these. The first stopped working after about 6 months. I bought another because I liked the product and figured the first failure was a fluke. The second one has now stopped working as well. This is not a complicated device - kettle, heating element, thermostat, switch and cord. It should last for many years, not just a few months.
