I have sent two (polite) e-mails and got an answer after 2-3 days, with payment address. I paid 2 hours later, and I got my tracking number about 55 hours later, but the shipment was made well within the promised 48 hours after payment. And the shipping was *very* expedited, just a bit more than 48 hours from Shenzhen to Geneva. So I have all reasons to be satisfied, especially in the context of (bad) business practices in the ASIC market.
