I'm impressed with the quality of the product BUT on my two lenses it vignettes. I bought it to be used with the Pergear 25mm which is notoriously bad with flaring, the vignette makes it unusable. With Fujifilm 35mm f2 XC works better but still slight / barely visible vignette in the corners. Overall for a more telephoto lens this hood is great, exceptionally well built, even the markings align in the middle after screwing.
Great quality, amazing price
