Bests & Worsts Reviews from Amazon

I just applied for this card about an hour ago and was approved within seconds for a $5k credit limit. The $50 sign-up bonus was added to my gift card account immediately. I also have a Chase Freedom card, and when I logged into my Chase account a few minutes ago, I was pleasantly surprised to see that my new credit card account had already been added there. What surprised me even more was that the Chase site is telling me my limit is $8k. Either limit is fine with me, but that's quite a jump in the span of an hour. FWIW, I have a credit score of 777, use very little of my available credit, and always pay it off in full each month. I've read a lot of the one-star reviews, but it seems (at least to me) that Chase has gotten their act together over the years. I'll update later if I experience any sort of problems, but for now, it appears to be smooth sailing.
