Comments about Bowens Bowens 60cm x 60cm (23.6" x 23.6") Square Softbox with Silver Interior and S-type Adaptor:

Softbox works well good soft light transmission but speed ring needs some redesign. Difficult to assemble.
Sides of fabric sag making wrinkles in defuser.
Used for head shots, table top and fill light.

Use for table top and closeup head shots. Overall useful however there are two problems. The "speedring" is designed to help the assembly. However it is also designed to allow only 1 of 4 ribs rotate. It is very difficult stretching the fabric on such a small box. I drilled out two holes to allow 2 of 4 ribs to rotate and the assembly is now is trouble free. Ribs bend allowing defuser wrinkling in front.
