Does this speed ring work with all the flashpoint softboxes ?
I have both profoto and photoflex softboxes. I also have both profoto and photoflex speed rings. I have not yet tried to use the profoto speedring on the photoflex softbox but I do think it would work. Generally the pole positions and holes are close enough from one speed ring to another. Octagon boxes may be a different story. if not, you can always return it, but I think it will work.
