Don't totally agree with you... currents can be small and noticable, but not not lethal. This reminds me when i was at a store who's display case with flourescents inside were failing. I leaned on it and got a similar feeling, although that was much stronger, and still not lethal.

firstly this happens with EITHER the thermometer, OR the UTH... I have unplugged everything but the UTH... i can feel it, and i have unplugged everythign but the thermometer... and I can feel it, albeit not as much as when the UTH is plugged in, on its own or at the same time.

not vibration, guratantee... AC adapter is a cube type sitting in the wall socket... UTH doesn't have an adapter, just a plug.

needless to say, nothign except for the lighting and ceramic heater i have are plugged in and being used now... they don't cause any problems
