Looking for the Snap-on style. Clasp are not dependable.

The happy strap 'clasp' come off at the most unexpected times. I lengthened the bra straps to accommodate the center pull with the happy strap applied. When it becomes detached my straps are much longer and feel like I'm wearing a strapless bra. A snap-on strap would solve this problem for many ladies, particularly with the bra designed to wear on the outer shoulder. I did not purchase the round center clip; I don't believe my bras have the additional length needed. My next purchase may be the specialized bra with variable strap placements.
