I also buy Dao Heng insurance in 05/2002, arround $760.- per 2 years.
And now renewal premium is $950.- for 2 years, and if confirm 15 days before expiry date then give 15% discount, so= $807.5, @403.75 per year.
I think it is not the cheapest one, but I feel it is OK la, and they claim the insurance is quite efficiency.
One time I claim the 門診, only give the original 門診receipt + policy copy, just OK, arround 1 week later, I rec'd the CQ.
