I got this as an alternative to the SRB filter i was using previously and quite frankly... its amazing. Its unbeatable for the price. I love the fact it has hard stops at both ends so you cant over rotate it and get that darkening and X pattern you get with most cheaper variable ND filters. It's also in a nice round case and has the stops scale marked on it. I did find its range is ever so slightly different from stated... it's about a 3rd of a stop under, but the image quality is great.

I tested this filter against some filters that I pay more for, and I would definitely recommend it!With the variable ND filter, you usually want to avoid the very end of the scale, and this is pretty much the same across the range. With this one, it's very easy to see where is the end of the scale and not over rotate it, which is happening a lot when you running around to pick up the footage with other filters. I would say it's either something like this or much more expensive filters within the range or 300£ or more. Don't go for anything in the middle!

Fantastic Filter, has stops to limit the twist in order to avoid the dreaded X shadow, it’s very cheap compared to other brands, and the quality feels very solid, clear markings on the filter to get accurate images, comes with a nice case to keep it secured
