Excellent
The shape of the shoe horn itself is perfect. It's flat enough with just the right amount of curve so it doesn't hurt your heal. Too many others are curved too much and your heal rides the edges and hurts. This show horn is just right.  The locking at the different lengths needs to be improved a little.  Otherwise it deserves a strong 4+ rating.<br />I bought 3 units - 2 for me and 1 for my brother.
