Small but very powerful flash. I have had it for about a month, without intensive use, but so far it works very well and cooperates perfectly with my Nikon D5200. Unfortunately, my camera does not support HSS, so I cannot evaluate this flash's capability. The LED light is satisfactory but does not work simultaneously with the flash, for example as a fill light. It has a built-in bounce card and diffuser, while the package includes a STOFEN and a stand. It fits well on the Hot Shoe but is a bit difficult to remove. Better than it falling off on its own though... I have not heard it make any noise like a buzzing sound that some foreign reviews mentioned during its operation. It only makes a small noise when zooming, but not particularly annoying. Also, the indications on the switches are tiny and I struggle to see what I have set each time. Finally, the screen is not clear in brightly lit areas.

UPDATE regarding my new Nikon D7500

The D7500 in Commander Mode with the Nissin as a Slave work perfectly together, in manual or TTL mode and adjustment through the camera, including HSS. All of this, of course, with Optical Wireless, meaning the commands are given by the camera's built-in flash. I have not yet tried connecting with radio frequencies. However, in HSS, it is not very powerful and needs to be brought quite close to the object being photographed to provide enough light.
