Purchased from Adorama. The hand is beautifully made and does a great job of minimizing ronin steps. The vest, however, is a different story. I'm not sure, maybe because I'm fat, but all the weight is concentrated in the lower back and I can't work this thing for more than 5 minutes. I run Ronin with Blackmagic Pocket 6k Pro. In theory, weight is not a problem. I can hold this camera in my hands for several minutes without flinching. However, with this system, the lower back pain is unbearable.
