Been with Atlas for a couple months now. Have nothing but good things to say about them. Atlas is the only book I know that has no restrictions or requirements on the bonuses. No rollover or 30 day wait. Nothing. Great CS. Large limits and friendly and honest clerks.
I really like their attitude. They like to be different and want you to stay longterm. They dont give a shit about what other books do or what people think. Everything you could want in a book.
