We are also with DKV. Like Cherina said, their coverage is very good and even covers IVF, but their customer service leaves a bit to be desired. They are slow to respond to email inquiries, though it is fairly easy to get them on the phone (if you have an IDD plan or Skype or something similar that will allow you to call Luxembourg cheaply - they don't have an office in HK). We haven't made a claim yet, but from everything I hear, they are good about paying them out and for high cost items like delivery, they can charge the doctor and hospital directly. Their best plan costs roughly 250 euros/person/month if I remember correctly, and their waiting period is indeed only 8 months.
