Well, the light sword is very good. It has a very powerful performance, I use it for filming. I was torn between this and the Yongnuo YN360 III. In the end, I preferred this one after seeing the specs and I don't regret it. I like that the Jinbei has removable caps and a power supply included in the package, along with a 2-meter cable, so I won't need to buy batteries right away because I can get my work done easily. It's easy to handle, with strong magnets on the back that allow you to attach it to a metal surface, and a very nice carrying case with a great little bag. I don't like that the app is not available in the Google Store and you have to download it from the company's website, which asks for camera and mobile photo permissions! With its quality construction and all the features it offers for an RGB light sword, the price of 138 euros is good. And let's not forget the additional 20 or so effects it has.
