The MIP tweak station gets the job done. However, check to see if the bubble level really shows level. Mine was way off. I compare the height of the ends of the pivoting arm, and ignore the bubble level.
Easy way to check bubble levels...... Place it on a reasonably level surface, note the position of the bubble, then turn it around, the bubble should be in the same place, if not, the bubble level is off. Hope that made sense.
