Great tool...but with an exception.
This is a very helpful tool, but it has one design flaw. The hinges I were using calls for a 1/8" spacing from the edge of the door to the edge of the 35mm drilled hole. This tool (without any modification) will only allow you to drill the hinge hole about 3/16" from the edge. (the picture incorrectly shows the jig upside-down) To correct for this problem, I had to make a metal insert that fits under the screws that forces the jig back from the edge of the door by 1/16". Once this was done the jig worked perfectly for about 30 hinges.
