Review on Ernie Ball 4003 Slinky Coasters by Gene Evans

These coasters are not as durable as I expected from an "industrial and scientific" product. Thanks to my knowledge gained in practice, I was disappointed with the quality of the materials used. While they do protect your tabletop, they showed wear and tear after only a few uses. The price is also too high for the short time they last. Save your money and invest in a more sturdy option..
