Rockler JIG IT Hinge Mortising System - Durable Low-Friction Transparent Door Jamb Kit – Easy to Use Jewelry Box Hinges System w/Hex Wrenches - Efficient & Versatile Cabinet Hinge Jig for Routing.

This thing is totally unusable. The insert that holds the template is not level from side to side. Mine is .06" lower on the right then on the left. This causes the hinges to not be the same depth on the left side of the box as it is on the right side. Better off making your own.

Terrible product which you need to buy additional pieces for... just make your own, google the type of hinge you want and type build jog next to it and follow the instructions, way more satisfying and much cheaper.

you have to also buy a template, bushing & bit which is only hidden in the last line fo the description.

This template is not accurate. I've taken two back to Rockledge and I am about to take the third back for a refund.
