This brush is useful. It is mounted on ball, very light, handy and perfectly silent on tiled or wooden floors. Its embedded stiff bristles do their office. It replaces advantageously the tip of my original Dyson C26 which while effective, is noisy on such soils.
The only less as compared to the original nozzle, is that there is no storage pin on the brush to hold the handle vertically on the vacuum cleaner. It's a shame.
