Although it does what it is supposed to do well, it is not likely to benefit you in your daily tasks
I bought this product to deal with the hinges on three doors for which I had to build custom jambs. It is not necessary to remove or adjust the hinges that came with the doors as the included bearing guides/templates fit seamlessly. I also had an interior/exterior door that required a custom jamb, and the hinges on it were larger than what could be accommodated by this unit. The hinges should be routed by hand. The procedure is quite simple, as it turns out. Trace around the hinge with a utility knife, score the wood slightly deeper than you plan to route it, and then proceed to free-hand it a little bit Routing by hand is the best option. Whenever the big chunk of wood gets close to the score mark, the wood will chip away, leaving these nice neat edges. For hinges that fit this unit does the design of the hinge for you, but setting the depth of the hinge is the biggest challenge. It is simply a matter of depth of the hinge The door itself has whatever is on it. Measure the depth on the jamb on the door, and you have your depth measurement.
