Just finished 80 minutes with both ankle and wrist cuffs (in front of me). Was quite an obstacle to post and chat with them. I even played a bit Civ VI while in them.
But now I am glad they are off and completed.
Nose shackle is still on, need more hours for that and won't finish it today (would have to sleep with it which doesn't sound right for completion).
EDIT: And two hours with the nose shackle done. That's 120 minutes of those 320 to do.
