Take a look carefully at the name. One is Logitech and the other one is Logicool from Japan. Im not sure if im the one who is lack of information or Logicool from Japan is one of the Logitech site as well. Logitech released this V150 Laser Mouse for Notebooks not long ago and today i received a news that Logicool released the same name and the same model of the mouse end of June. Is that clone or the real product from Logitech?
