While the adhesive on the trough is very aggressive, it will (or can) dry out and lose its grip over time. However, this could be decades.
Using the trough with a magnesium arm and a Decca Gold cartridge resulted in no sonic difference here, so unless you have an early aluminum wand, I'm inclined to agree with ct0517 about its usefulness.
