The Albrecht's 2 cents:
This is IDEAL for removing your post to stash in a car. Since the lever holding mechanism is not round, your adjustment will not spin looser or higher, leaving your torque exactly where you had it set. This extends the life of frames and protects carbon fiber seat posts from damage of over torquing.
