I received a ASI533MC box with inflexible round USB cables and thought my dealer had replaced the cables.
Why doesn't Zwo no longer put USB flat cables in this box?
I never had any problems with the flat cables.

The ZWO USB3.0 data cable has been upgraded to a round design, providing enhanced flexibility and stability while minimizing interference.
