Some one makes a lot of money on the back of brand names by importing Grey Imports. So many things from many different fields. once I thought I had bought a good quality, brand named item only to find out later when it did not work as intended that the 'brand name' asked a few questions and got the serial number and said sorry, contact the seller and get them to fix it as it is NOT covered here in Oz.
Seller was not a happy campaigner.
