3-Way Adjustable Extension Pivot Arm Adapter Set- Long & Short Straight Joints Connector Convertor 35mm/50mm (2X Same Direction + 2X Reverse) for Gopro Hero Series, SJCAM, GeekPro ect.

They tighten up very well and seem like high-quality injection molds. They worked well when installing a DJI Action Cam on my helmet. They were higher quality than what came with the mount, and I like the one low-profile screw. Cheap and effective!

Useful additions

I only needed one of the four pieces but, the price was right and it worked perfectly. no real issues getting it installed and once I used a screwdriver to tighten it up (just as I had done with the others in the same project) it held perfectly and showed no vibration in my Garmin that was mounted to it.

I needed an extension option for a fixed mount for a GoPro. This product is a good value, fits standard accessories, and has lots of options for different sizes and angles.

These work as they should. Just as strong as name brand ones and fit in the name brand ones as well.

Perfect but wish there was a wrench

The item is good, but I wish you could buy individual pieces.

Arms fit great with generic and gopro parts. 2 out of the 4 adjustment screws cracked and fell apart within a week or two of use. Not sure if I trust the arms to not crack as well, but they seem to be doing fine.
