I haven't been able to tell if it's better than other capos I have from, for instance, Ortega. The only detail is that it's tension/grip is very strong. So I have to use more effort to place it on the guitar as others, which kinda makes me feel like it should do a better job because it holds the strings down with more power? I am not sure. But for fans of Martin Guitars like me, this is already my favorite capo :-)
