Excellent quality and functionality for a dual and variable filter
This filter is great if you want the convenience of a dual filter (CPL and ND) and a continuously variable ND filter. It worked perfectly. However, note that due to the physical structure of the lens, adjustment is a little more difficult, but this is not a problem of the design or this company. It's just the nature of such combination filters. Also note that this filter is of course twice as heavy as a separate filter used individually. This means that balancing a lens on a smartphone can be a bit more difficult when using a gimbal. I was still able to use offset weights on my gimbal.
