Ok, so here's a question for you, what's the difference between the MK shaver socket and AFAIK, every other dual voltage shaver socket on the market. They all seem to be 20VA rated but only MK produce one which is suitable (and even that's not certain) to be used with an electric toothbrush.
Now given that rechargeable toothbrushes are becoming ever more popular, it is surprising that most new sockets are still labelled as "Shavers Only".
It seems that toothbrush manufacturers think it's ok to use one otherwise why would they sell a product fitted with a two pin plug??
