I should set up an acquaintance mobile Internet on his new laptop. As low as is. So off to the supermarket with the 4 letter, which begins with A and worried SIM and embroidery. After the stick initially extremely poor and then not work anymore, I have him simply returned and ordered it here. Kam in 2 days, has been installed nd worked immediately with good reception performance and super fast start. I can make this stick only recommend. He ran here on Windows 7 Home Edition 64bit. My friend who is quasi PC novice, the operation was immediately totally easy and for weeks happy with his laptop in the allotment house :). Even in the countryside best reception. Again a recommendation !!!
