Here is a Steadycam which, on paper, looks good for a small camera GoPro or other action, with friendly prices. Alas there is absolutely not compete with other more expensive. It is very difficult to balance, I had to weigh my camera and add weight down, but even it does not prevent the pitching in all directions. Walking, running with is impossible, the camera continuously balance the right to left. I'm not a pro steadicam, maybe I have to train me ... still, it do its job, and allows stable planes. Overall it is doing well, the materials are good, but if it does do that while we pitch film, it was not used much ... other more expensive models are probably better. I regret my purchase.
