The phenomenon of the filter does not fall off, especially in cold weather.You cant spin it properly with your hands and want to remove it quickly... frustrating.Even this, the wrench is wide and easy to grip so you can easily remove the filter.In addition, it has a structure that catches lens protectors, ultraviolet (UV) filters, polarized (PL) filters, and ND filters, so it can be used in a variety of filters and situations.
