The build quality of the endpin itself is fantastic, it enhances the sound of my cello better than the carbon endpin from Bois d'Harmonie (B&H), which I've been using for years. My cello now has edgier articulations and more grounded bass, without feeling heavy on the bow. The only thing I miss from the previous endpin is the tip. The tip from B&H carbon endpin is made of tungsten carbide and practically never dulls. This tip from Otto Musica dulls rather easily and does not have the silver-grey colour of titanium. Therefore I assume it's made of stainless steel. Although this tip is replaceable, a dulled tip is the nightmare of all cellists. It's really a shame that the only let down of such a great product is the tip.
