Fidelity-wise, they are a very good mid-point between lo-fi tungsten and high fidelity diamond cutting styli. They have much more clarity and high end and a very low noise floor when compared to tungsten styli, but they don't require heat or vacuum, and are less expensive than the hi-fi diamond styli.
Your results will vary depending on equipment and experience, but we typically get at least 200-300 7" sides at least out of each one. Once the needle starts to get noisy after typical use, you can rotate the stylus in the head a couple times to get new, quiet faces.
Notice: Styli vary by unit. The stylus you receive may not look exactly like the ones picture.
