So far so good, been using the card for a year. Simple and hassle free with unlimited 1.5%, there might be other cards from time to time that offer higher rates like citibank, 1.6% (cashback plus card) that I would recommend as I only knew about it later. But, if you have accounts tied to SC, 0.1% less doesn't matter too much.
[Cashback Card] [Bill Payment]
The SC Unlimited Cashback Card is a card I used when the transactions do not earn good cashback rates from my other credit cards. I use it mainly for bill payments and government services.
Nothing fantastic. Just a card to earn some cashback.
