Vignette is noticeable, but for its cost and with a lot of light it’s not so intrusive.fraction of more professional ones. Very very nice build quality

By far the best value for the money
You can spend a TON more on a "nicer" fader, or a set of multiple ND filters, but the quality from this is great, and since it's variable, you don't have to carry a bunch of filters around, just 1. This filter gets you 95% of the quality of higher end filters at 20% of the cost.
