10-14 days in Transit, that's 10-14 days after it says despatched to overseas. A month for things to arrive from China is normal, sometimes it can be quicker. The quickest I have recieved anything from here is 14 days via China post and the longest was 35 days via Singapore post. I usually get my parcels 17-25 days after they have left Fasttech (to the UK)

Edit
17-25 days not business days
