I've double checked the date and it's a new post.... So it performs the same way as my Gardiners long arm swivel, the old swivel that apparently isn't a true swivel so they brought out the new one that fits closer to the pole but doesn't have the quick loc. Didn't see the point in that one and from the vid I can't see anything different from the old swivel so a close up is needed.
Definitely a close up is needed if you could do a video for us please . Your version seems a lot looser than the Gardiner version I have been using for the past year or so.
Correct it gives you smooth orbital action instead of a side to side action.
And as said before give you equal pressure no matter what angle you are using it at.
