Apparently the last time I serviced my SA System 2 reel I lost a small part, the drag knob lock ring.
I could have lived without it but I sent them a e-mail asking about how go about getting a replacement.
A week later, not only did they send me the missing part free of charge, but they sent an extra for the next time
So here is a public thanks to 3m Scientific Anglers for their fine service
