The dreaded 'cross' or 'butterfly' effect comes when the two elements are not lined up properly. Sometimes that way from the factory, sometimes from repeated use. It's not difficult to unscrew the retaining ring with a rubber stopper and rotate on element until the cross is gone at maximum ND.

Thanks! This is great info. I thought about buying one at one time or another but now I know to avoid these things. The tests are quite telling.
