Query: Fine for rough work, that's all

These were okay for rough stuff, but they didn't hold up well over time. We ended up buying top shelf brushes ($15-20 per) at our local hardware store for fine work or for highly visible areas. Those we still have. The Linzer's were tossed long ago. If quick n dirty is all you need, these will serve. You get what you pay for.
