There are no complaints about the brush unit. It looked like the original, was easy to install and worked great for 6 months. However, belts are a different story. After only a few uses, they seem to stretch enough to slip off the spindle. I will return them once or twice before throwing away the old one and trying another. Since today it's finally my turn and I've just ordered original ORECK belts. I believe the roller brush will make my first purchase a success.
