As others have mentioned here, it's ridiculous that Plantronics forces its customers to purchase a replacement set of 3 different sizes, when all I needed was replacing the broken ear piece of the size I obviously know is the correct one for me. Why not offer packages with 3 ear gels of the same size, instead of forcing customers to order two sizes they don't need, in order to get the one that fits. Absolutely outrageous! For this idiocity I'm giving it only one star, although obviously, the product itself is OK.
