Good quality
Works as expected. Took a bit of tuning to get the PID right but holds temp well once calibrated.

Okay but tricky
The part itself is fine, but installation instructions were vague for a beginner like me.

Perfect Upgrade
Installed easily on my Neptune 4 Max. Temperature stability is noticeably better than the stock unit.

Solid replacement
My stock hot end failed after a year. This kit was a direct fit and works perfectly without modifications.
Q: What is the warranty period?
A: We offer a 90-day warranty against manufacturing defects.
Q: Is this compatible with the Neptune 4 Pro?
A: No, this kit is specifically designed for the Plus and Max models due to size differences.
Q: Can this handle ABS filament?
A: Yes, the ceramic block helps maintain the higher temperatures required for ABS printing.
Q: Do I need to recalibrate after install?
A: Yes, we recommend running PID tuning and checking Z-offset after installation.
Q: Does the kit include the cooling fan?
A: No, this kit includes the hot end assembly only. You should reuse your existing fan.
