I've tried various tracking sites for parcels from China, and they never seem very good at all - most you get seems to be "it's been dispatched" followed by "it's been delivered". But to be fair, even some of the big UK/USA carriers have crap tracking as well "your parcel will be delivered to day between 9:00AM and 8:00PM" - thanks a lot for that!

VERY few have good tracking, such as 'some' Amazon deliveries - "your parcel is x drops away" - and shows a map where it is.
