It doesn't do much. The ring is just a cheap celluloid foil, so fragile that it already comes with marks and bends. It is so light that it doesn't sit flat on the drum, and therefore doesn't kill the harmonics it should kill. Better invest a bit more on something that works. If you don't have enough cash for the king, the Big Fat Snare Drum Steve's Donut, then at least the Evans ring should work better.
