Hoping to use this in Spain outside wifi cafes. It certainly worked when I tried it from my parked car approx. 200yds away from free wifi sites. The Alfa adapter was received quickly by post, wellpacked and the C.D. supplied installed it with no problems. The aerial attaches to the laptop lid with a suction mount and is very neat. Well satisfied with service. The point of using this device is not to avoid paying for the price of a coffee but not occuping a table when the premises are very busy and thus depriving the proprietor of extra business.
