This just arrived in the post , super impressed. Laser cut 1mm stainless steel and all the line loops and GoPro connectors are bronze welded on , beautiful job. I previously ordered a couple of plastic ones that were just crap ($5 each) and just didn't trust them , so I came across this for $25 delivered.
Still really light but heavier than the plastic but I will run the GoPro Cube on it so weight wise so should be much the same a plastic mount with GP4.
Just thought I would share. I have nothing to do with these guys.
