 When driving the screw, use your free hand to *gently* twist the secondary buttons **clockwise** (away from the PCB). This will ensure that the distance between the buttons and the switches is correct.
 
+A common problem that occurs once the top is placed onto the mouse is that these buttons will become stuck. If that is the case, take the top off the mouse and adjust the secondary buttons. You can twist them either clockwise or counterclockwise by about a degree or so, while keeping them flat against the base. Eventually, you should be able to find a position that allows the buttons to operate correctly.

 The plastic parts can flex to accommodate the angle at which the wheel is inserted. Nice and gentle, now.
 
+Gently give the scroll wheel a spin. It should spin freely with no resistance. If there is resistance, take a screwdriver and hollow out a bit of material from the scroll wheel holder until there is no resistance. Be careful, though: if the fit is too lose, the scroll wheel will jostle during regular use.
