General I bought this to complement my DJI Osmo to allow me to house a microphone and LED lighting kit. I saw this in a YouTube video and decided to buy: Packaging: It came in a small box with stuff to keep it safe in the box. instructions were included. It was sent in a small Revain box and is well protected from possible damage. Pros: It was some kind of metal, aluminum I think. It felt good. It didn't feel like cheap plastic. Very well done. The wheel for driving the bolt into the chamber had a notch to keep your fingers from slipping. Minuses: The instructions were in very small print and difficult to read. Recommendations: This is a quality product.
