- This is a (cold) shoe mount. There is no electronic communication with the device above the shoe. - The bottom nut/dial works well to secure the adapter however the top nut/dial has never worked well for me, in aligning my external battery or flood light. I just screw in the device and hope that it bottoms out in an alignment that is acceptable. - I have only used relatively light weight devices but have seen stripping of the black paint on the bolt.
