I'm pretty new to using routers, and edge guides.  I've had some trouble  learning how to setup the edge guide for accurate depths.  However, that is  part of my learning curve. The Edge guide was very easy to install on all  the PC 693PK router bases I have.  The micro adjuster also works well.  I  expect to become more proficient at using this edge guide soon, and I'm  sure I'll be even more happy with it then.
