It really is great! I think it performs so well because of the really thin bristles. It loads up a lot of lather fast and releases it with ease. Plus it is very soft. I'm happy you enjoy it as well!The Cola Yaqi is one of my favorite brushes for looks, feel and performance. I like smaller brushes & the 22mm loads up lather like a much larger brush.
I have several Badges and am not impressed with any of them, but the Badger Sagreda Familia is an exceptional brush, a top performer along with the Cola Synthetic.
