*Update* I'm increasing this to 3 stars. After the initial loss of bristles, the brush lasted a few months. I use this brush to remove soot from the end of laser burned wood. The brush immediately started falling apart. I've only been using it for 2 days and the bristles are already falling out. The first hit on the tree and the bristles fell out. The cheap brushes I bought from Harbor Freight hold up much better than these. I can usually get out of them for a few months before they fall apart.
