At maximum setting, it's still not usable. I think it works up to 5 stops. It's still nice alternative to expensive filters.

I'm not sure what I expected for such a cheap price, but it's not the greatest but not terrible. I use the ND mostly for video so I can't really comment on photo quality, however in video I notice some glaring and overall degradation in video quality. It still works though. Might invest in a better one later. For now, it'll do.

Not a 5 star product because it definitely brings sharpness down more than higher end filters, but hey this isn't a high end filter and doesn't cost the same amount as they do either. It's great in a pinch for some fun shooting, could get away with some client work also. It's nice to have a variable around when you want to pack light and have options. No weird colour hue to this either, just a neutral exposure cast.
