It works well right out of the box (some assembly required). However, not as good as it could. I modified mine and siliconed all the seams and used foam gasketing tape to affix them to the table. This resulted in zero dust below the table, cleaner operating routers, and significantly quieter operation- I'd recommend the cabinet to anyone for a nice upgrade, but I firmly believe you need to silicone the seams and add a gasket to get your monies worth-
