The ligature is very easy to install. You don't have to turn the screw many times to fix the reed. It makes a difference in the sound, making it noticeably more stable and darker compared to cheap Chinese metal ligatures (some of which are surprisingly good). But it should be noted that the price is too high. In some stores it already exceeds 190 EUR. It is much smarter to buy an excellent Yanagisawa soprano mouthpiece for 170 EUR, which comes with a corresponding Yanagisawa ligature - which is noticeably better than this one. In addition, my copy came with a soldering error, so the screw holders were not soldered parallel!
