I like the cashback, whereby you don't need to claim or choose "rewards", it's automatically deducted from your statement. But the credit limit is poor. Given that I have a perfect credit rating and a significant income, it is a measly 20% of my previous Amazon card account. (I cancelled because the reward scheme ended). I hoped that after 6 months they would increase it, especially since I have consistently been shovelling in large amounts of money to buy those items that exceed the credit limit. Unfortunately, the increase was quite small. I suspect they aren't that interested in someone who doesn't pay them any interest. If you are in the same situation I recommend you have another resource, because it can take several days to get a transfer into your account to ensure enough credit is available.
Cash back applied directly to statement
