First, the picture accurately describes the product and the price is obviously easy to see. It is a stiff bristle brush on a stick.
Second, I was looking for a brush to clean the inside of a 5 port, 5 L reaction vessel. The product worked, albeit awkwardly, on the bottom and partway up the side. Angle limitations of the head and the rigidity of the stick have me looking again for a wire handled option that functions better. It would, however, probably work adequately for any glassware that had a port with a less rounded shape and/or entry ports larger than 1.5".
