The Domani product is unique because it combines magnetic and mechanical forces to secure the clip-on. It uses only two magnets on the frame with their peripheral wall and their horizontal surfaces exposed, which are receivable in the open cavity, provided by the steel cap of the clip-on.

The structural interrelationship of those two parts, whereby the female lug 'clicks' into place over the male lug, provides the secure attachment of the clip-on that is appreciated by the active wearer.
