I ordered a couple of these from Graham and one worked fine, the other one didn't fire. I returned the faulty one got a replacement yesterday, the replacement didn't work either. I have tested it on both an SB-600 and an SB-900.
Graham tested the replacement and it was fine and he says that SB-600s sometimes have this problem, something to do with the connection being loose.
Has anybody else had any problems with these and is there a fix?
Graham has offered a refund but I was wondering if maybe tightening the clasp of the adapter may help?
