The brush actually looks quite well made. But when you first use it has left on the disc unfortunately seeehr fleine scratches. Looked almost like streak, but can not be removed. I think the hair are not truncated at the top, and are still so sharp that they cut into the plate. will try on a metal edge or round so.
but actually very disappointing that that has not been made at the factory!
a disk brush, the plates scratched actually the last thing you can do ..
