Works great, only issue is not just with this product, but all Profoto attachments use this rubber system, which is very strong, and secure, but can be difficult to mount to strobe when up in the air trying to attach a large softbox. Needs fiddling/wiggling to get it on, especially if you're trying to push ing up to the 10 marker on the Profoto's. Best suggestion is to put the softbox on the floor, put the strobe face down into it, then once attached securely, put it back on the stand.
Bought this for a profoto octa box. Fits perfectly and easy to assemble. Great value
As good as the Profoto OEM part
