TLDR: they had no complaints about the headset or the adapter, but they had trouble pairing the controllers over Bluetooth and even when they did work they would regularly drop out
I think I got lucky. Purchased an adapter before realizing my 2070 super had virtual link and wouldn't require it. Additionally, paired the controllers to motherboard Bluetooth with ease. Been playing half life alyx and it's incredible. My biggest complaint right now is how the controllers are basically converted from an index or vive controller scheme and sometimes the on screen tutorials don't match with what you're supposed to press.
