The shoe horn works.  However, the wrist strap broke while taking it out of the package.  (Very difficult to unpackage.  Use scissors!!)  All the seller could tell me was that he has sold hundreds of these and he has never been told that the wrist strap was broken.  Well, MINE BROKE DURING UNPACKAING!  He stated that it was easy to fix because the tip screws off.  That may be true if the little string wasn't broken on the wrist strap.  Well, MY LITTLE STRING IS BROKEN.  Thank goodness that the wrist strap is not a necessity for its operation.  It works okay...
