TOZ TZN-S03 Universal Rotary Extension Arm Mount Set for Gopro Hero 7 6 5 4 3 3+ 2 1, GoPro Accessories Kit Extension Arm Adapter Pivot Arm Thumbscrew

Pros: Remarkably sturdy for how light it feelsCons: The tolerances are a tiny bit loose, so you can still muscle the arm around with the screws fully set, BUT it's not so loose that it'll jiggle out of position on it's own, so it's a non-issue as far as Im concerned.Final notes: Bought this for my helmet in May of 2018 for gokarting. I bought the mount about two months later. In November of 2019 I bought my first bike and have been riding it weekly ever since. Through all the usage, shaking, and torment it has taken it's still holding up a year and a half later. My only suggestion is picking up a handful of inch long M5 hex screws like I did to replace the thumbscrews for a lower profile. If I didn't I wouldn't be able to set my helmet down on anything without it resting on the mount itself, but that's just the way my setup is.Update June 2020: still strong :D

Was able to achieve. Nice chin mount GoPro with these adaptors

So far no problems I really didn’t know what parts I needed to get my digital nightvision setup so I kit kinda winged it but it worked I only need the 1 part they do kinda feel cheap but kinda sturdy but still cheap lol hard to work it but we’ll see how they turn out if I don’t come back everything’s held up good! Got him pairs up with a surewo mount

Meshes perfectly with gopro gear and aligns right where I need it to.

Plastic is not as high quality as official gopro stuff, but it works absolutely great for its purpose and for the price quality is better than expected. Works great for its purpose, holds the camera just right, secure at high speeds, and got a lot of positive feedback from others. Do pay attention to the shape of your helmet though. Some wont accomodate a gopro mount on the side due to contour. Price is a big factor in my 5 star rating. If this was $50 it would get 3-4 stars.

On bumpy roads it wants to rotate downward so I had to tighten it. Today, 13 months after I bought it, it broke and fell on the road. I think this part in aluminum would last longer.

I needed these in plastic to save weight. Others I bought were to flimsy and would cause a shimmy in the drone. These do not. They are well built and fit together tight. Bought two sets so I could combine pieces together with out any twisting causing no shimmy when connected to my drones.

I ordered these to supplement my motorcycle helmet Go Pro mount. There were some reviews that claimed these were of inferior quality compared to authenticate Go Pro mounts accessories but I did not find that to be the case. They worked well my my other mounts, with fit and finish being indistinguishable from the Go Pro branded counterparts.All that was missing was the Go Pro stamp of approval. I think you can purchase these with too much concern or worry.
