Review on 📷 Goliton 90° Rotary Extension Arms Mount Rig Screw - Compatible with GoPro Hero 9/8/7/(2018)/6/5/4 Black, Hero 3+, DJI Osmo Action, AKASO/Campark/YI Action Camera by Kevin Kue

Good value for money. The only problem is that they're harder to put on than stock GoPro gear. It seems that the distance between the folding baffles is slightly smaller than on the GoPro. Fit but loose. No problem for my purposes.
