U**1
Poor quality
After several months of use, the filter has a stain in the middle that distorts the image quality by creating color discoloration, the stain cannot be cleaned because it is created between layers that can be seen in daylight.Impossible to contact the seller.There is no warranty policy.
M**T
Bad quality and not 400 stops
The stops don’t work as intended… you can’t feel the ticks and it just goes all around….Basically doesn’t function as required…. Better spend some extra money and buy a better quality one
