Overall good quality for a great price. Easy to use and setup and provides decent soft light.
I am using it with the Godox AD200 pro speedlight and it might not be the softest light ever, but it is absolutely acceptable and for the price there is no way to complain. Kit includes an inner baffle/diffuser and the large outer diffuser giving a much softer result than the bare bulb or fresnel head. With some experimentation you can definitely get results that are high quality enough for client work etc.
The S2 bracket gives a wide amount of adaptability with different accessories and lights. Bracket is mostly plastic and doesn't feel bomb proof, but it feels durable and high quality enough and again, for the money I cannot complain at all.
This is also a very travel friendly and compact setup. The softbox folds down into a curcular carry bag and it along with the mount fit in a small carry rectangular case that measure about 11.5 x 9 x 6 (rough measurements). There is enough spare room in the case to also fit a small folding reflector, spare batteries, cables etc. Paired with the Godox AD200pro and its case these take up a very small footprint in a bag and make it really easy to travel and fly with a high quality one light setup.
Definitely would recommend.

I needed a softbox or other diffuser to use with my speedlites for a headshot / portrait session with three wonderful women. Naked speedlites would not do!
Despite the low price I decided to take a chance on these softboxes, and now I'm amazed at how terrific they are. They pack-up small, assemble easy, have adjustable brackets for my light stands, and include hefty clamps for my speedlites. Highly recommend.

I have used these with speedlites and also continuous (3 x 20W LEDs) lights. The results are terrific - nice soft light.
I was a little nervous about the bracket and how the SB mounts to it, but it's fine. Surprisingly sturdy even on my light-weight stands.

I’m a photograph on the go and this is a great simple set up. Easy to use, light and portable!

Quality again at an exceptional value; picked this up to do some product photography as well as some other jobs I have lined up and I can’t imagine a product being so straight forward. Ease of use was perfect you can take it outbid the box and use it. Build is great as I’m notorious for breaking these products the first time I put them away and this has held up for 5 different events so far and looks like brand new. I never hesitate when purchasing a Godox product and I’m constantly reminded why.

Simply put, this Mounting Bracket allows me to use the this Softbox with my Speedlights and Studio Flash Units with no tinkering between projects. It sets up and folds easily, is very light weight and creates a soft light in a portable portrait kit. I have not used the grid yet but plan on trying it near the background to see if it helps control edge bleed.
