Review on MOSHUSO Ballhead Adapter Monitor Microphone by Robert Oner

Plastic). Nowhere is it written that the bars are made of steel. I wouldn't buy if I knew. I bought these to add dual LED lights to my snorkel cam and salt water quickly rusts the steel posts. I'll try to keep them lubricated but I doubt it will last long. However, these are VERY powerful mounts! They can hold a lot of weight and can be tightened to keep the accessory from moving.
