After bending yet another of the stamped-metal shoe horns, I was cautious about trying a plastic one.  I really dig the hard-steel ones, but they're hard to find.  So I gave this a try, feeling odd at paying more for shipping than for the item, but either way less than for a martini while out.

It's a good shoe horn.  The length is nice, it is thick enough to be sturdy but yet still thin enough to be functional.  I doubt it will last five years, but should easily last two.  And the plastic is really smooth - very slippery against socks, which is a very good thing.
