Work great on deeper snares (5.5"+), not at all on pancakes (<4") . The fact that TAMA are installing them on their high-end snares must mean a lot. When the snare "likes" it, it becomes very sensitive - that's one change in addition to the tonal improvement. Some reviewers complain they broke too easily on them, but IMO that's because they SHALL NOT be tightened as much as other "ordinary" wires - because of the shape of the individual wires, they are designed to work under less tension.
