No more nozzle erosion

I was going through brass nozzles every few prints with glass-filled nylon. This hardened steel assembly has lasted months with zero degradation. Highly recommended.

Perfect for Carbon Fiber Prints

Finally upgraded my A1 Mini to print CF-PLA without worrying about nozzle wear. The installation was straightforward following the official guide, and the print quality is exceptional.

Essential for serious hobbyists

If you plan on printing anything other than standard PLA, this is a must-have. The durability is impressive, and the hotend assembly feels very solid.

Good value for money

Works exactly as described. The only reason for 4 stars instead of 5 is that the silicone sock fit was a bit tight, but it settled in after the first heat cycle.

Great upgrade but needs calibration

The hardened steel nozzle works great with abrasive materials. Just remember to run the flow rate calibration after installation to get the best results. Very satisfied overall.
