The sleeve adjustment variable left a very good impression from the first moment. Its build quality is excellent - a robust mechanism, no jogs or wear, with smooth and precise operation. Its threads are clean and work perfectly, allowing for easy and stable adjustment. The finish is meticulous, without imperfections, and generally shows that this is a product of high precision.
In practice, it offers very good adaptability and convenient adjustment, allowing you to set the length or position with great precision. It doesn't loosen easily, holds the setting firmly, and gives a feeling of confidence. Even after a lot of use, it shows no signs of wear or play.
Despite the many positives, the very good build quality and the functionality of the movement, in the end it unfortunately did not fit as it should in its intended position.
