Vgood Generic PCI-e 1X/4X Card to NGFF M.2 M Key PCIe Slot Adapter

It does work, I verified at PCIe gen 2 speeds. I have not been able to check at Gen 3 speeds.I only gave it 3 stars since it only connects 2 PCIe lanes and does not connect all 4. I could not find anywhere on Amazon or Micro Sata Cables website where it details it's really only a x2 adaptor and not a x4 adaptor.
