A company that sales battery for all kind of power tools and electronic devices. When I first purchased something from them, the internet address made believe that the company was based in Switzerland, from where I was making the order. But it happened to be that the company was based in The Netherlands and the battery I order was coming from Hong Kong in fact (something not mentioned on the order page). Therefore, I had to pay custom fees when I received it. Moreover, the battery is not even original, how could that be an upgrade?
