The all-new Third Generation iLok holds over 1500 licenses in a strong metal case that works with all iLok-enabled software and features a sleek new design. This new edition is half the size, twice as fast, and holds three times the amount of licenses as the 2nd Generation of iLok. It is also fully backward compatible with the 2nd generation iLok, so if your software shows that it works on the 2nd generation iLok, it works on this new generation as well.
