Who It’s Best For
The CM-5.3 is best for regular cyclists who ride several times a week and want to maintain a quiet, efficient drivetrain.

How long do the internal brushes last?

Is it better than manual cleaning with a brush?
It is more thorough because it cleans all four sides of the link at once and uses a constant flow of clean solvent, which a handheld brush cannot do.
