I haven't tried the cheaper versions, I can only tell you that the H-R version works just as it should.  It's functional, and as thin and light as it really can be without being flimsy at all.  It makes the band thicker, so you may want more than usual to take the watch off while typing or other activities where your wrist rests on something for long periods.  Still, nice unit, lends a little class.  Pair it with a nice alligator band.
