Then we went to test: Conclusion: super part and very well made.
Disadvantage: I use a Glidecam HD2000 with Panasonic GH3 + battery grip. I adjusted the spring of the arm on the easiest level, but my setting was still too light. The arm hit of metal on metal, Weili the spring was very excited. This made the use of pointless. Therefore, I had to send back the part!
Please consider beforehand, with which setting you used the vest! cheers
