Question about Godox AD200 Pro

Supplement to the first answer. Basically, all light shapers with a Bowens connection fit the S2 adapter. With the Godox light shapers, you have to be careful not to get one with the smaller Godox connection, which looks almost the same. Unfortunately, this is not clearly described in the product descriptions.
The cheap Octaboxes are almost all those that cannot be opened and closed quickly. They have to be put together laboriously. Completely unusable on location. Many of the more usable ones are not available.
I can only really refer to SMDV Speedboxes (google). They are first class and can be opened and closed quickly. They are the best light shapers I have seen so far. Pay attention to the Bowens connection there too. By the way, they are made in Korea.

The range in this area in this shop here leaves me a little perplexed. It's a jumble of suboptimal products from dozens of manufacturers. Even well-known manufacturers like Elinchrom, Profoto or even Broncolor buy the light shapers cheaply in China (presumably from Jinbei), stick their name on them and triple the price.

I have had very good experiences with this Octa Softbox. Very quick to set up, robust, good quality of light, etc. Diameter is 66cm.

Westcott Rapid Box Switch Octa-S (Price Digitec at the moment: CHF 214.-)

I would take an SMDV Speedbox with about 80cm. Super processed and extremely quick to set up. Not cheap and not available in this shop.
