The Rockler 62525 Dovetail Jig comes assembled and includes a router bit and guide bushing. The four-page instruction sheet is brief but easy to follow, provides safety instructions, and includes clear pictures, but no parts breakdown. A bit more detailed information, helpful tips, and reminders would be useful. 

Once set up the jig is quick and easy to use. The top and side offset guides are one piece, allowing them to be adjusted as one unit for even spacing of the joints.  The fence is adjusted based on an equation that considers the diameter of the router base, material thickness, and router bit diameter.

Veritas Micro-Adjust Wheel Marking Gauge

The adjuster runs through the beam from a small knob at the back end right to the cutting wheel, which moves in and out as you turn the knob. This arrangement works well but makes adjustments a two-handed operation, requiring a little more effort.
