@Didou I know that cheap price is attractive, but in the long run it may not be the wisest path to take, especially with things connected to high voltages. When I mentioned the 4 'fake' power supplies back up this thread the thing that alerted me to be concerned was the fact that the power cables sent with them broke THREE electrical safety regulations in the UK. People are importing dangerous items and using them unawares. Its frightning really as there was even a case of a child being killed by a fake games console bad power supply. The risks are real. If you understand spoken English there is a TV program called 'Fake Britain' which i believe is on the web too. It follows investigations into all sorts of fake and dangerous items that get into the country. It's a very enlightening watch.
