I turn my cards and refund without problem via Amazon, still the TOP!
Edit of 11/12/2012
3 things to know if you buy these cards:
1 - it takes PCI-e 2.0
2 - must ALREADY SATA 3 on your motherboard (no need on old configs even AHCI)
3 - you can use 2 eSATA or SATA ports at the same time (or 1 + 1 eSATA SATA)
Here the seller's technical response (very nice by the way):
Dear Valued Customer,

First, this card need one PCI-x1 slot epxress with a Version 2 and second, your mainobard to-have-have a SATA3 chips derived, namely your mainboard supporting SATA3-have to, if not, this card can not help you to reach this best performance for SATA3 SSD.
