Who only seeks a filter to try long exposures, or with an open visor want to film under sunlight, I can only recommend this filter! Of course, the filter color distortions to know, depending on the setting, the image is slightly blue or slightly yellowish. However, can be very good repair with a manual white balance problem. Other side effects such as a softer image and a cross-shaped sticker can be observed only at very long exposures at the maximum darkening.
The build quality is acceptable. The filter is made entirely of aluminum. However, I realized that's true, the label for the minimum and maximum adjustment in any way, here it is the exposure simulation camera to trust!
All in all you get for the price is a functional product for beginners to definitely recommend!
