-The Godox Propac 960 makes a high-quality and solid impression. The cables (for Metz) act massively and resistant. I can not tell the difference externally to significantly expensive Walimex product. On the American side, there are some Amazon reviews and were then also decisive for purchase.

The Andchlüsse sit tight and everything works perfectly. Additionally, I have then still the Walimex PowerBlock USB connector bought in order to possibly invite my phone can. Again, there are no problems with the interaction.
