I have used Stork-up for over a year and have concluded it is beyond terrible. Highlights are I had set instructions on where to ship a order to the US contact. The HK contact overrode it and had it sent to HK instead of China.
They are very difficult to communicate with, with lost emails and on followups. But they are very good at emailing all of your email accounts you have EVER contacted them with when payment is due.
Patrick, upper level manager, actually threatened me, saying "I know where you live" via iMessage, when an invoice became overdue. We were going through some hard times then.
Needless to say, I am no longer with them.
