I've ordered about 100 shipments from them and received about 90-95% of them, probably due to the fault only of the local postal service. Lots of junk on there, but also lots of decent quality items. You have to shift through and know how to shop to find the sellers selling high quality items. My favorite shops sell titanium wares and titanium jewelry.
The only thing is that shipping takes about 4-8 weeks. I usually forgot what I've purchased before it arrives. I've never had to pay customs fees, however.
I used to order a lot of green tea but they are no longer allowing the sale of food stuffs at the turn of the year.
