Not well designed.
Not Quite sure what your designers were thinking , by adding a " FLIMSY" Spring, at the bottom of the Shaft, just above the Shoe Horn. That's the area that NEEDS to be RIGID, To Control the Shoe Horn, once its in the shoe. You may need to push or pull a little, to help manipulate your Foot into your shoe. This Spring "Collapses" under  the slightest pressure.<br />Not sure how this product moved past the TESTING phase of development.<br /> Could not get any of the " Twist to Lock", feature to work at all.<br />The Extending Handle , is fine. ( The overall concept is good. LOOSE the Spring. Work on the Twist Lock. )
