The instahot is my favorite appliance in the whole of creation. I use it for making tea and coffee. It also provides a boost for boiling pasta or making rice. And I use the boiling water to clean fry pans and broiler pans after cooking. 

This is the fourth instahot I've purchased. Unfortunately, the tanks start to leak after a while, requiring replacement. Don't ruin your cabinetry by assuming the tanks are solid; leave a pan under them just in case.
