Alex goes back to Amazon and sorts reviews by most recent . Dozens of 1-star reviews: “Driver CD is useless. Link downloads malware? (Windows Defender flagged it as PUA:Win32/InstallCore)” “Works for a week then stops. Support email bounces back.” “The driver installer tried to install a VPN toolbar.
