Just my point. I am just not very technically adept. If the blow dryer suffers from the wrong type of electricity (sorry for the untechnical term) then can you imagine what happens to more complex appliances like a notebook computer or a mobile phone with the wrong power supply!

Bergevorges point on people bringing their own dishwashers from the US or UK. I can imagine that people bring their own kitchen appliances from the US because things are different in Europe. Washing machines on mainland Europe are not toploading. Refrigerators usually don't come with ice cube makers and in the typical US-sizes (i.e. tank-sized). Also European kitchen drains usually do not have a shredder built in.
