I spent the early part of my engineering career as a quality controller, rising to manager, in a precision engineering factory making electronic and clockwork timers. So I have some experience of judging if something is fit for purpose. And the SRB adaptors, in my experience and I have 5 of them, are.
I do take the springs off some, and I do leave some on the lenses. But I use some as they are intended with no problems.
