You know you're dealing with heavy-duty quality when you have to mount a light to the accessory! The design is solid, the lenses swap out easily. It also has great heat dispersion. I have used this with my Aputure 1200D pro and it was surprisingly cool during use.
The gobo holder and cutter blades create endless possibilities in creative lighting design. I often use the Spot light and cutters to project a square beam onto a large reflective or diffusion scrim to create large over head bounce without the need to rig any heavy lighting up high.
It comes in a solid case with custom stiff foam, and 3 of these stack nicely.
