I agree with Robertster. There is too much play in the micro-adjust feature of this edge guide. I use it with a DW618 router. I really like the router but I am disappointed in this guide. In addition, I am having a little trouble finding what the increments on the micro-adjust represent.  I guess I can hack my way through a project with this guide but if I was a Pro, I would be annoyed. This guide feels like it was designed as an after-thought
