I haven't even used it. The image in the listing gives the impression that the video is running full width. The roller is very small in both width and diameter. I just gave up and bought a real Dyson nozzle. In the second photo they are side by side, you can see the difference. One of the biggest advantages of a soft roller is that it doesn't have a front flap, so it picks up large debris and is easier on hardwood floors. This third-party tool defeats that purpose, and it's also incredibly small.
