I only use this card when i know that i will spend >$2000 that month and these transaction doesn't earn > 2.5% cash back in other card category.
Honestly speaking, i don't really like their internet banking layout. It doesn't seems very friendly to me. Therefore i always rely on the paper statement to make payment.
My experience with their customer service officer isn't fantastic, they didn't get back to me on the queries i highlighted.
