We're working on it, but now we can ship quicker than she can (once we get inital orders out).... we've got them in stock on US Soil.... Plus we take credit card, check, MO, paypal so there's less risk sending money to china.... and we offer ABSOLUTELY FREE tech support (my job is technical sales/support) and advice on building packs, chosing BMS, charging, etc.
From my dealings with her before, she's VERY SLOW if not unreachable unless you're putting in an order..... Once we got our cells, she promised me BMS cables and replacement cells.... neither of which I got. She was slow to answer on order status.... she always had an excuse. Plus shipping air is not really "legal" from what I hear. Both shipper and reciever can be liable for fines.
