The packaging could be better but then the cost goes up, right? Not a DIY tool. Do not use this in your Riobi router! The double cutter is heavy and seems unbalanced, that may be true, but when you're spinning that much weight, only the mic can drop it. therefore, it vibrates greatly during spin-drying. at boot it formed well. You must check all nuts before attempting to use them as any new tool can cause harm, safety is on YOU! I used this on a 1.5 standard pine for a custom shelf. I did it with three master passes and one finish. I used a Porter 693 cable on a 4 x 8 "Paul workstation" with Jess Em Rout-R-Lift 2. This setup was safe and efficient. You need to adjust the spacing on the double cutter to make the connection fit your needs. Remove the nut and remove the gaskets as needed.
