Title: Not very good as a "tool" adapter
Review: Based on the shape, you might expect that this would be sized to fit *inside* of power tool dust collection ports. Unfortunately, that's not the case. The steps seem to be designed so that each one has an *outside* diameter that matches a standard size, plus there's no taper to the steps which makes it unlikely to fit anything except hoses. If it's intended to only be used to adapt to other hose sizes, then it shouldn't be advertised as a tool adapter.I'd recommend the Fein, they did a better job of thinking this through.Fein 921072K13 Step Adaptor
