I use the jig a lot and have great sucess. It is accurate, strong, adapatable, and well designed. The screws hold well and I have not had any splitting. The vice grip type tool that hold the faces flat is somewhat a pain to first set up but works well on repeats. Keeping things lined up while fastening is the hardest part of the job. The pocket joint is very stong and is not that noticeable. Works well in both hardwoods and softwoods with the supplied screws. The screws are also great to use by themselves.
