Awesome tool
Very easy to use, only issue I had was the location pin was a bit tight. Chucked it in the drill and polished it up with a scotch-brite and it worked perfectly. The end to end symmetry made it easy to move from one side to the other. Good price as well!

Excellent 11 hole jig
Size: 11 Holes
This jig worked excellently. It doesn't have any instructions, so I watched the video of it. I set it up the way the video showed, and I got decent results. Deducted a star since no instructions.

Good jig
Size: 11 Holes
The jig itself is great. The markings make it easy to be consistent; the design is well thought-out; and the build quality is good. I would recommend replacing the drill bit, though. A nice brad point will serve you better.
