The build quality is at a high level, so that you feel good is when you hold the softbox in hand. The fabric (nylon) is durable and withstands even rougher deal. The seams also make a solid impression, so I'm sure that this softbox will serve its purpose for a long time.
The insides of the nylon fabric are equipped with reflective foil, which the luminous efficiency improved. The white diffuser fabric is really white, making the flash soft.
This softbox can be attached by the Velcro on any ordinary shoe mount and does not slip so easily.
For transportation you can fold it and place the softbox in a supplied bag, so they do not take up much space in your pocket, making it an ideal companion.
I am completely satisfied with this investment and can recommend this softbox each.
