Review on SUNWAYFOTO Indexing Rotator DDP 64M DDP64M by Keith Montague

I needed a second panorama head and wanted to save money on the Manfrotto 300N that I already have. Unfortunately it was a bad choice, at least for me. Sunway's degree adjustment mechanism is similar to Manfrotto's, but when I tightened the adjustment pin (tighten fully, which I think should be, since the pin has a built-in stopper, and that's how Manfrotto works) I actually ended up with the drum's coating scratched, and in the process my 20 degree stop became so rough it was practically unusable. The paint chips now peeling off the drum also clog the small roller ball in the spigot, which is annoying. Okay, I just moved to 24 degrees, but now I have to be very careful not to overtighten the adjustment pin or I'll scratch the drum again; If I don't tighten the pin, the stopper is so soft that it doesn't always snap as I drive from stop to stop, and it's easy to miss the stop and turn too far (I shoot at night, so it's easier , missing a stop than you think due to the darkness). My Manfrotto has a nice crisp click and stops right where it's supposed to. Maybe my Sunway copy is just defective as other reviews seem positive, but I'll probably buy a second Manfrotto.
