As the name suggests, the brush works but was not assembled properly. The plastic end caps on the bearings were installed on the wrong ends and one of the brushes on each side of the belt is rubbing against the metal brush cap. This brush replaces the one that came with the Kirby when I bought it over 10 years ago so all is an improvement. It seems to pick up hair better, but it still wraps around the brush. Update: After a few months of use, I'd say it's not working as advertised. The brush head fills up with hair to the point where performance is affected. You have to stop pulling out all your hair and then move on.
