I've been using the PX-500 card for nearly 3 months.
The card is easy to install and the connection speed is just outstanding.
I live in Rhode Island, and work in southern Rhode Island.
No connection problems.
I visited Concord, New Hampshire. (several hundred miles away from home)
No connection problems.
Great for checking e-mails, surfing the web, watching online videos (like YouTube).
I've downloaded movies from ITunes, etc.
I'm not a Gamer... so, I don't have any feedback for on-line video games.
I selected the PX-500 card because I didn't want to tie up a USP Port with an internet connection.
