Query: DO NOT BUY IT

Package arrived without user's manual. Had to download the manual from StarTech web site. Followed the instruction to install the drivers but my Laptop complained the device failed to start. Contacted StarTech tech support and instructed to install the manufacture provided drivers which crashed my laptop. Returned the card 2 weeks later. DO NOT BUY IT, Period.
