Not the safest for self belay

No, the Shunt is not the safest for self belay under ALL conditions. See the user instructions. In overhanging terrain, the angle to get the lever working may be to steep (overhanging).
However, for the designed use as a mechanical prussik, as a backup for abseiling, this piece is perfect. When you need to rest for longer - when you clean your route from friends and rocks - this is far more comfortabel to release than the old style prussick.
