For the most shagged element still in working condition category.
See:
Image shows a working twin MI element removed from my grill with split in outer casing revealing the coiled element and insulation.
And yes, that is the scale ruler visible behind the element, through the fully split casing.
Element was functional on removal (57 + 42 ohms) with 15Mohms to outer at low voltage.
The other half of the twin was split too but not as impressively.
Can anyone beat that?
