I'm glad I bought it! quality is strong!
I now understand why K&F Concept products are made from brass. It is so resistant to torsional deformation and the screw easily fits filters from different manufacturers. Previously, I bought the "MARUMI Step Up Ring Made in Japan" on Amazon, and there were no problems at the beginning of the purchase, but after repeated use and careful storage, it gradually became unfit. In fact, I was quite impatient because the ND filter didn't fit on the outdoor site. Conclusion! If you're buying a large diameter like 82mm, I think this K&F Concept brass piece is the best because it's strong and sturdy!
