Lightroom brushes?

Lr 6 stand alone lacks the whites / blacks in adjustment brushes, so i was looking online and there seem to be some brushes. I miss not having those two so i downloaded some freebies today and hope to check them out in a day or so. Not much of a fan of normal presets but the brushes sound good if they are like they sound to be.
Has anyone tried additional brushes for Lr?

what are u trying to do? Do not the adjustment brush, tone controls and radial filter do what u want?

With the filters and brush it would be nice to have the blacks and whites to use. Not available with Lr 6 stand alone. On landscapes i like to use it - as i did some when i had creative cloud.
