Perfect Replacement
Fit perfectly on my Kobra 3. The installation was straightforward and the print quality improved immediately with better flow consistency.

No More Clogs
Switched to this all-metal hotend to print PETG and ABS. Haven't had a single clog since installation. Highly recommend for abrasive filaments.

Solid Build
Good value for the price. The hardened steel nozzle is a nice touch. Make sure to level your bed again after swapping the hotend.

Good Upgrade
Solid build quality. Prints nicer than the stock hotend. Took off one star because the instructions could be more detailed for beginners.
