Review on HSU (7 Pcs) All Aluminum Alloy Curved Extension Arm Kit Metal Pole Mount Helmet Stick Extension Arm Mount For GoPro Hero 11/10/9/8/7/6/5 Black,Session 5/4, DJI Osmo Action And More (7.9”/5.3”/3”) by Sam Faucher

This is a great kit if you need curved extensions for certain shots, or to put your camera in a certain locations.The extensions are very sturdy, and weigh next to nothing.I got this kit to modify my gopro location on my helmet.This extension kit allows me to move my gopro so the lense is centered on the helmet like the viewer sees exactly what you see, rather an offset shotThe middle length extension matches the curvature of my helmet exactly (Helmet is a Ruroc)The aluminum thumbscrews are always a great thing to have, especially when like with this kit, they include a wrench to make sure the camera mount stays tight.Unlike Cheap plastic extensions, these are threaded internally so you never have to worry about losing the acorn nut for the thumbscrew.These extensions have a neat party trick, in the larger end of the extension, they have a 1/4-20 screw mount so you could adapt these even further, or mount these to your tripod etc.Overall great gopro mount extensions, well worth the ask, and an essential product if you need certain shots, with no plastic twist and shake.
