It's the first time I've ordered from them so I don't know any more than you guys, I'm afraid. But they replied to my order on Monday within a few hours, and then again shortly after I paid to say when my order would be sent.
Other than the fact that they make these adaptors, I really know nothing else about the company. I hope your orders go through soon.
Edit: Oh, and it's a very basic operation shopping-wise. They just sent me the details through e-mail and gave me an address to pay through PayPal. I get the feeling they don't do a lot of online sales, or perhaps mostly wholesale stuff. I'm guessing all the NDS Adaptors on Yahoo Auctions here come directly from this company, bought in bulk for a discount.
