We will admit that we think these rotary tools are some of the coolest things around; you can do so many things with them. But once we saw this attachment, we were blown away. If you don't have the money or the space (or the inclination) to set up a whole router table assembly in your home or shop, but you still want to put decorative edges on wood projects, this is absolutely the ticket. It holds the tool under the table, and you mount your shaping bit in it. Turn it on, run your piece against the stationary tool, and your edge is routed. It also works great for small dado grooves with a straight bit. The new table surface is even smoother than before, and it's plenty big enough for small craft projects. It's also a great setup for sanding: Just chuck in a sanding drum and move your workpiece against it. If you've got a rotary tool, get this.--Kris Jensen-Van Heste
