Peace be upon you, there is a Ronin from Zion Company. It is almost new and has only been used once for testing. Its stability is very high and its performance in carrying the camera's weight is very reasonable. Search on YouTube for Ronin Zion or its name attached to the box and see all its specifications and features. The reason for selling is that I have another one and don't need it. The sale is flexible and open to offers. Before making an offer, check its new price and make a reasonable offer because it is almost new. Thank you.
