This is my first Festool accessory. I purchased it to facilitate the residual dust removal from the kitchen cabinets I am sanding and repainting. I love the shape of the nozzle, it fits easily into the nooks and crannies to remove all but the very smallest sanding dust, (for this step I use a tack rag). The bristles flex easily yet retain their shape. When brand new, the nozzle requires a little muscling to properly attach it to the hose. It has gotten easier the more I use it. This was a great purchase to complete the set of my Festool 125 EQ 5-in random orbit sander and CT 36E 9.5 Gallon HEPA Dust Extractor. A good investment that will enable me to get a professional painted finish on my entire kitchen cabinet re-do.
