The one's I got... and I think that jmur got... aren't exact clones and I think the main change is even an improvement. The original only has one rod per coiler... these others have two, one on each side which doubles the size of rods for each.
Mine have the previously mentioned difference in the rod that spins being longer which I'm not sure is good or bad... but they also didn't mark the sizes on mine which certainly isn't a plus... On the plus side though, mine are knurled and not smooth.
