Are KlickFix pannier mounts any good?

Quoted message said:

It seems that many pannier makers use the KlickFix mount system. It's
used by Ortlieb, Altura, Jandd, Carradice, REI, Jack Wolfskin, Agu,
Cannondale, and more.

Arkel has their own mount system but that's beside the point.

Has anyone here had problems with KlickFix pannier mounts, or are they
really the best thing going in mounts?

Thanks for your help.

I have two--one on each bike's handlebars. They were extremely easy to set
up and so far, no problems at all have arisen. At least they don't cause the
bag to sag like the old Velcro attachments.

Late response, but after a few years of using the Knog panniers with KlickFix, I'm sold. I've used them on three different bikes, all with racks that have different diameter tubing. The shims included in the setup have accommodated all changes through the years.

Wonderfully engineered, and surprisingly durable.
