So there I was checking R.C.D.s in holiday chalets. It was the last chalet. The blinds were drawn, the power was off and I went to the meter cupboard which is situated above the kitchen work surface, in a cupboard, to gain access to the R.C.D. Then it happened. Somebody had left an aluminium torch, stood on end, in the cupboard. A booby trap. I knocked it, it toppled and fell onto the glass ceramic Smeg hob and broke the glass. Long story short.. I got a new hob and went to fit it. Unfortunately, against the maker's instructions, some fool had set the old hob on a bed of silicone. It was glued to the work surface, which meant that I had to break even more glass to remove it.
But this did allow me to see inside. They are not worth the money. A few spiral heating elements under a dark glass top and some fancy control circuitry.
And the are easily broken.
