I have 4 Moon Unit Indexers running on my four Universals.
The .45 and .38 SuperComp machines get the heaviest use and
I see no signs of wear on the shell plate, base or anywhere else.
I frankly would not run a Star without a Moon Unit indexer.
Once the machine is set up with the case kicker (if you taper crimp),
and functions well, then add the Indexer. The only thing I have to do
is watch the case feeder, primer and put a bullet on the charged case.
I can knock of 50 rounds in a very short amount of time.
Ray has done a wonderful job on the Moon Unit.
