I bought it. The keyboard works, but touch pad is a no go. If you can’t get the keyboard to work trip the BT and GD and plug it in. It will pop up with a drive. Open said drive and download the zip file from the sellers store page and then drop the .uf2 file into the drive. The drive should disappear for a sec then reappear. Then the key board should work.
As far as getting the touch pad to work… I am stuck there, I’ve tried reaching out to Arya/Crimeir, but haven’t received a response back. So the issue going forwards with qmk will be adding/reverse engineering the driver for the pixart trackpad[1][2] that is something that is outside my skill set.
