Fairly easy to install.  Just follow the instructions and use the template provided.  I used a square just to be sure I had it parallel with the cabinet.  Works great - even to the point of the door fitting perfectly.  Installation tip for the door face:  initially, leave the door on it's original hinges, install the drawer, close the drawer (push all the way in) then use a rubber band to hold a sharpie in the holes that will secure the door face.  When you close the door, the sharpie will make a small mark on the door exactly where you need to drill a pilot hole.  Repeat for each of the four holes, install the door and you should have a perfect fit.  Very happy with the results - so much easier to access every baking sheet and muffin tin now instead of digging and banging through the cabinet.
