I have a more than 10 years old "Cullmann Clamp".
It is a really handy and stable support for Cameras or Speedlites.
But I managed to break of the clamping plate (pictures attached).
So I wrote a mail to Cullmann Germany describing my problem and requesting a replacement part.
They answered within 3 hours asking for my Address.
And 2 days later a free replacement screw was in my mail!
I think that is an excellent example of great and uncomplicated customer service.
I am very positively surprised by that and wanted to share it.
