A fellow photographer told me about Strobepro. I bought two speedrings recently and they arrived promptly and were excellent quality. I will buy from Strobepro again!
I bought three speed ring inserts that were made for Profoto, to adapt Profoto to other brands. They have wide strong flanges that can be modified to more equipment than other ones that I've seen. The price is so good that I may buy more instead of trying to make do with just three.
Fits the system well, holds the weight of large softboxes well.
High quality product!!Thanks a lot!!
