I snagged these in a deal. Beautiful Security capture cards. They were lightly used for a short period then sat unused per the seller. I applied new thermal paste as a precaution. They are in mint condition. Working fine when the system was put out of service. Hard to really find much information on them. Seem like a very niche item. I have 2 of them. I am still studying up on them. As of right now they are (As Is). If I figure out a way to test them I will update the listing to reflect what I find.
