Have used it for about a month. Not on a regular basis though. Does the job perfectly well when its tightened to the right amount. Usually doesn't need to absolutely tightened to its brink which is good. However, the durability and the longevity is what I'm slightly worried about. Hopefully, it'll pass the test. I must mention it is buzzfree and accurate across all strings unlike clip on ones which may spread uneven tension across different strings based on the neck radius.
