It is light weight and promises to excellent at damping vibrations but you have to use CA glue to attach the large perspex plate to the gel dampers. So this is definitely NOT quick release. Also, as I am quickly coming to realize in the multi-rotor world, it comes at a hefty price for what it is.
The Kopterworx adapter isn't great for a heavy camera or windy conditions. I found the gel dampers too flexible.
It also puts the gimbal too low for the standard retracts so you then have to spend another few hundred euro for extended legs.
