I have been using CDK services for a while now and I must say, they have been average in terms of performance. Their website, cdki.co.kr, is user-friendly and easy to navigate. However, I feel that there is room for improvement in their customer service. The response time to queries can be quite slow, and sometimes it feels like the customer support representatives lack knowledge about their own products. Overall, an average experience.
