Poor advice, unless by inspection you mean unwinding of transformers, replacement of fusible resistors and X- or Y- class capacitors, and so on :P

There's no need to unwind anything with a small SMPS like that, just see that the transformer secondary isn't wound with that pink/yellow triple insulated wire and it can be assumed junk. AFAIK that's the only way to make the little ones legal, and that wire is always terminated with flying leads or an offset bobbin so it's easy to see.

This mat doesn't look very good but thats fairly typical for these heaters.

What I did was ground the metal enclosure section and run it from a dedicated GFCI outlet. Since there is really no way to protect from someone cutting into the heater element, unless you want to isolate the entire device.
