I bought these on sale to replace the old beaters I normally use for watercolor. They are a big upgrade. I'm impressed with how much water they hold and how well they hold a point. They have the perfect snap for me (I'm not a fan of really soft squirrel hair or synthetic squirrel brushes).
As a set, they represent a tremendous value and are pretty much all the brushes someone needs for watercolor or gouache painting. And as long as I don't use them for acrylic paints, I think they'll last me forever (I may come back and buy a second set for acrylics).
