Summary: It is cheaper then taking apart the laptop, loosing screws, damaging ribbon cables, cussing, doing it all over again because you did not get a card or memory stick seated properly, yelling and cussing some more, then throwing the old cheap laptop away out of frustration.
Summary: Bought this for an older laptop that can't run a USB wireless. Installed the software, installed the card, connected to the internet. What more could you ask for? Speed and range is normal for what the card is.
