PCIE X8 to HP FlexibleLOM

Have anyone tried Tobias Schramm’s HPE FlexibleLOM to PCIe adapter or one of the derivates?

HP uses a format called FlexibleLOM for expansion cards in many of their servers. It’s basically pcie x8 with a “lip” so you can’t use them in a standard pcie slot. The FlexibleLOM cards are really cheap and these adapter makes it possible to use them in a full height slot.
