I was offered this card, and chose not to get one. Based on what I remember, the pro was no preset spending limit. This could also be construed as a con, though, as at any time they can say ‘nope, we’re not willing to extend you that much credit!’ That could play hell with planning. I believe it was a rewards card, but it also came at a steep price (annual fee). I already have an American Express ‘Blue’ card, with no annual fee, a decent interest rate, and rewards. I found that to be plenty for my purposes.
