Good quality, stiff cable
Works great, temperature readings are accurate. The cable is a bit stiff compared to the original but manageable within the chain.

Solid spare part
No complaints. Fits perfectly into the Nextruder block. Price is reasonable for a backup component.

Fixed my heating error
Had a thermal runaway error. Swapped this in and problem solved. Glad I keep spares on hand for emergencies.

Genuine Feel
Seems like an official part. My printer is back to printing PLA without issues. Fast shipping too.
Q: Is installation difficult?
A: It requires basic tools and disassembly of the hotend. Please refer to the official Prusa manual for guidance.
Q: Does this include the brass nozzle tip?
A: No, this kit includes the heater cartridge and thermistor assembly only. The nozzle tip is sold separately.
Q: What is the maximum safe temperature?
A: It is rated up to 290°C, suitable for most common filaments including ABS, PETG, and PLA.
Q: Does it come with thermal paste?
A: No, we recommend applying fresh thermal paste during installation for best heat transfer results.
Q: Is this compatible with Prusa MK3S+?
A: No, this is designed specifically for the MK4 and XL Nextruder system. The MK3S+ uses a different hotend assembly.
