All in all a good product. The quality looks good! Everything is made of metal and makes a robust impression. The adapter rings only have one thread, which I can screw onto my lens (in my case 49mm). If I want to mount a polarizing filter, etc., I first have to put the screw filter and then the adapter on top of it. What I also noticed is that the adapter ring sits very easily in the filter holder. Is kind of like a steering wheel which you can easily turn several rounds. A small rubber lip (on the adapter or on the holder) might still be a good product!

I bought the filter holder system together. The adapter rings cover all possible lens diameters, are made of metal and made to fit perfectly. Because of the tight mechanics, I always equip the actual filter holder with slots for a maximum of 2 filters before I lock it to the adapter ring, which is less fiddly. The holder can be rotated effortlessly so that an inclined course is possible, but it holds well and does not slide further by itself. The filter itself is also very secure and has to be pushed with force, which secures it against falling. At the price maximum purchase recommendation!
