CWWK SFF8643 Extended 4*M.2 card adapter Only suitable for Q670 4-net motherboard

Unfortunately, this product doesn’t work on my Q670 NAS board. I reached out to support but never received a reply, so I still don’t know if there are BIOS settings or adjustments needed. At this point it feels like wasted money.

I was surprised by how fast CWWK CS contacted me on my email request ( after earing they were no so good ), that we were even going back and forth with emailing on a Saturday!
They attend my request so quick and I did the purchase of a item that was no longer in the shop and dispached quick as well, as after a dew days I had it.

5* guys!

Can anyone tell the size of this device?
It seams the CWWK support is not able
