I have one and used it a little bit, the only reason I don't use it is the mounting location is not level on my boat, and leans or slopes out towards the water causing the rod holder to be further away from me than I prefer. Nothing wrong with the rod holder mount itself. I don't think the holder/mount itself will give or move on the assumption you have the wingnut tightened down securely. If you have one on the left side I would recommend you get a left hand threaded rod holder from driftmaster so the rod holder itself will not spin or come loose when a big fish gets on.
GO BIG ORANGE !
I meant to behave, but there were just way too many other options available at the time.
