The Ruby Nozzle 0.6mm by DUROZZLE is a game-changer for Elegoo Neptune 4 Plus/Max users seeking durability and precision. Its genuine ruby tip ensures exceptional resistance to abrasive filaments like carbon fiber, glass-infused, and metal-filled materials.

Users report outstanding longevity, with some nozzles remaining like new even after 18 months of use. The brass body guarantees excellent thermal conductivity, while the funnel-shaped design minimizes material buildup and clogging risks.

Compatibility is seamless, with direct replacement requiring no settings adjustments. However, some users note the need for slightly higher temperatures to achieve optimal flow rates compared to standard nozzles.

Print quality shines across various materials, with PETG particularly benefiting from this nozzle's capabilities. Its ability to handle higher temperatures and resist wear makes it a worthwhile investment for both abrasive and non-abrasive filaments.

While the initial cost may be higher than standard nozzles, the extended lifespan and superior performance make it a cost-effective choice in the long run. The responsive customer support further enhances the overall value of this product.
