Since there are no actual reviews of this filter yet (Sept. 2022), I'll chime in briefly to say I just got it and it looks very well made, the glass looks great and the soft edge good to my eye. Have not had a chance to try it in the field yet, but will report any issues if any. Based on appearances, I'm giving it 5 stars for now, subject to field use. This was the only filter I found anywhere near this price range that has 4-stops of graduated neutral density. I find that the more common 3x is not enough at times. Although it's called part of a "square filter system" on the box and in the manual or product guide, this is in fact a standard 100x150mm RECTANGULAR filter. The manual is in several languages; the English part is written in better-than-average English with pretty good descriptions of other products available from this company. The weird thing is the box it came in, which is somewhat over-engineered with a magnetic clasp. But better than a cheapo box I guess. The actual filter "pouch" or rigid envelope containing the filter, within that box, looks like something jewelry might come in, or a fancy wallet perhaps. It looks like real leather (may not be but well done) in brown and gray tones, with an orange tab you pull to get the filter out of it. More magnets holding the clasp closed. Nice but probably added 15% to the cost and a little too much for my bag but you may like it for yours. I stuck the filter in my filter holding box in my camera bag where I can access it more quickly as the sun goes down.
