Opticfilm 120 vs. Opticfilm 120 Pro - I'm confused

[Hassasin]

Looking at Opticfilm 120 it appears what they called 120 Pro has been "updated" with a plain 120 ??? At least that is what associated files appear to suggest (Pro back to 2021, 120 from 2023).

What is 120 Pro then, compared to plain 120 ? Nothing apparent in specs with exception of interface going from USB 2.0 to USB 3.0.

Has Plustek improved on anything ?

And speaking of this scanner, how are film holders performing / holding up ? I have seen the claims.

I'm further confused since looking at it now, it appears that 120 Pro had the 3.0 USB and the "new" 120 is showing 2.0. A Plustek typo ? Hard to fathom USB 2.0 being used in 2023.
