T580-LP-CR 2-Port 10/40GbE Low Profile UWire Adapter with PCI-E x8 Gen 3, 32K Conn QSFP Connector

Absolutely nothing wrong with these cards. Except that this listing is not for a Chelsio T580-LP-CR. I ordered this card three times and each time I got a Chelsio T520-BT. The boxes have an inventory sticker for the T580-LP-CR on the top, but the label on the edge is T520-BT. One star, should be zero, because Amazon's inventory management is screwed up costing me time and money.
