Strange... my friend's PT57A is almost exactly the same as his Trisys PT280 (China batch) which was supposed to be 20mm when I compared them side by side...
Whereas, the Prestige Pro that I got is slightly thicker at 21mm or 21.5mm...
-- Donno whether his PT57 is a fake or not, which I heard about that a lot.
The PT10 (Prestige mids paintjob) is definitely thinner at 19mm though.
