Makes my workspace so clean and works like a charm!m. Plug in your tool, hook up your shop vac, and it turns the vacuum on and off. I’ve got it running with my miter saw and router, and it kicks on instantly when I start cutting, then lingers for 10 seconds to clear the hose. The build is solid, with a thick UL-certified cord and flame-retardant casing. Really surprised with the quality and I would say it’s worth every penny
