Love the product from the quality of design and construction, however it's somewhat pricey for it's expected to do. If you have some time you can build a router guide easily (search youtube or other sites) with a combination of scrap wood and parts available at your local hardware store. Have to admit that to some degree this Dewalt guide adds convenience and precision to your work, but then wood working isn't super precise. I know folks who had taken pride of building their own guides but I took the easy route!! Only reason dropped a star is due to the price, but otherwise it's a well machined product. I'm using this on DW618B3 and fits them well. Since this guide doesn't fit the Dewalt router case, for this price you'd think Dewalt should throw in a carry bag.
