SmallRig Strip Softbox Reviews

Impossible to Assemble

I literally spent 45 minutes in combat with this softbox trying to assemble it. Putting together a softbox should require breaking a sweat.

Build quality is excellent

Overall first impression is that this is a very nicely made softbox. The rods and fastening system are thick and seem much more durable than comparably priced softboxes I have. The exterior rods are a nice touch, and keep you from having to mess with supports inside the softbox itself. My only qualm is that I wish the long-edge of the strip box was more tensioned. It's a bit floppy and the diffusion material isn't held taught as a result.
