Question: How do you connect the softbox to the ring that goes around the flash unit?  Mine didn't come with any instructions.
Document: Mine arrived with NO instructions. The ring & bracket are sturdy metal (good) but don't accommodate my LumoPro speedlite. I have scraped mine up, trying to make it fit. I found a YouTube video of a similar product to figure out how the ring goes in without ripping the softbox (stretching is involved), but still can't get my flash to fit properly in the metal hole. It would be really nice if there were a rubber flange or something to allow flexing for slightly different flashes.
I was expecting the inner diffuser to come with this one since reviewers have indicated that they did get it with the inner diffuser. However mine never came with the inside diffuser so I asked Neewer about it and they basically told me that I can refund or have them replace it (shipping at my own cost). So now I'm stuck with it because shipping for this would have been like 1/2 the price of this unit already. The stand and the ring was good though.
I have the ePhoto version of this. It's basically the same unit with minor differences. Construction is good. Isn't the most polished but it's fairly solid. I'm glad they made several improvements since previous version. They rubberized the edge of the rings so it doesn't tear up the softbox. They reduce the length of the track so the softbox can angle downwards now.Mine did not come with a inner diffuser panel nor did I expect it too.
The unit fits in a well made canvas bag smaller than a shoebox. The box's inner difuser is held with removeable metal clips on elastic bands. I was glad to see the ring bracket has a rubber gastket around it which protects the softbox from tearing when it is attached. The box has an adjustable vertical travel on the bracket to accomodate different height flashs.
I did modified the bracket on mine, by putting some soft material around the rings and covering it with duct tape, this was done to avoid unnecessary wear and tear on the fabric of the actual box.I do wish mine had come with an inner baffle diffuser (the only thing that stops me from giving it 5 stars), but as it stands, it is a good buy
Mine did NOT come with an inner diffuser....just the outer one. However, using my 580exII with the flash's built-in diffuser flipped down overall lighting seems very even. (For kicks, I shot directly back at the softbox and didn't notice any uneven pattern until I dropped the flash power down to 1/16 and upped the camera's aperture to f/16 or so at 100 iso in a dark room.
Nothing to complain about and does exactly what it's supposed to do. The material feels nice. I don't have any other softboxes to compare it to, but it definitely doesn't feel cheap like I kind of expected it to be.CONS:Like I mentioned earlier... although it is very solid, the metal is kind of "rough" feeling and is not very smooth when sliding around the flash and softbox ring. The metal is very sold and secure, it needs some sort of coating.
I actually like this unit better than the Cowboy Studios version (CowboyStudio Photo / Video 24in Large Speedlite Flash Softbox with L-Bracket, Shoe Mount & Carry Case)-The contents of both this and the Cowboy Studios softbox kits are virtually identical.-This one has a simpler tilt mechanism than the ball head on the Cowboy Studios softbox.-The metal ring on this unit has a rubber edge which gives a more secure and snug fit with the softbox.
This is a nice product for the cost. There are no instructions, so I am going by the product picture to mount the softbox on the bracket by inserting the metal ring between the back edges of the softbox. This method makes the softbox droop a little from the weight, so it's a little tricky to aim the softbox exactly on a light stand, but it can be done with a little trial and error.The L bracket is a bit too short to fit my particular wireless trigger under my flash.
My front baffle covers the softbox perfectly. Setup is a breeze, takes me less than 2 minutes. For those people who have trouble putting it back in its pouch, youtube folding softbox and you should find tons of instructions.My setup is a Canon 580EX II mount on a Cactus V5 and they get mount on the included speed ring. With this setup, the flash is just barely inside the softbox  when the Cactus V5 interferes with a know on the speed ring mount.
