The 2pcs Kobra 3 Hotend Hot End Assembled Extruder Printhead Kit seems to have garnered a mixed reception among customers, with significant criticism regarding quality and performance. While some users appreciated the factory fit and ease of installation, others reported serious issues that make this product questionable for Prospective buyers. Several reviewers highlighted the manufacturing problems, particularly with the brass throat, which reportedly did not fit securely with the heat sink spring. This led to failures during printing, including parts dropping out and causing damage to expensive components. Users also experienced persistent heating errors, with temperature fluctuations that rendered the hotends unreliable. Instances of leaks at the throat were common, leading to concerns about the overall durability and longevity of the product, particularly given that some leaks occurred after just a few hours of operation. Although there were a few positive experiences where users found them compatible with their printers and appreciated the non-shearing nozzles, these accounts were overshadowed by frequent remarks about design flaws, inadequate fitting of components like fans, and general dissatisfaction with performance. Many reviewers expressed frustration, stating they would not purchase the product again, emphasizing the lack of reliability compared to OEM parts. Overall, while the Kobra 3 Hotend kit might appeal to those looking for low-cost replacements, the recurring issues highlight the risks and frustrations that may arise. **
