Ender 3 S1 Sprite Extruder Hotend Heater Block Replacement Nickel Plated Copper Heatbreak High Temperature 300℃ Plated Copper Nozzle for Ender 3 S1 Plus, Ender 3 S1 Pro,CR-10 Smart Pro 3D Printers

Excellent product, at least as good as the original, perfect fit.

I recently bought a new ender 3 s1 pro and within a week the stock heater block failed. I bought this one and it took less than 5 minutes to install, 5 minutes to calibrate and the prints are noticeably better! Highly recommend for anyone looking at this.

Works well, fits with no trouble.

Bought this since a rogue print melted hotend and i couldn't recover from it, so had to by replacement.Easy to fit, look same that was on it, run couple 12hrs prints and no issues so far

I tried this in my printer and it wouldn't work. Measured the resistance of the heater and it was 0 Ohms, in other words short-circuited. I just hope it hasn't done any damage to the motherboard!

Product fitted and working in 10 mins.After test print printing with pla+ petg and abs were easy.Did a few temp towers and all came out great.Overall I can recomend as it does what it's supposed to and prints quite smoothly.

Really great product seemed to get the A B Temp Fault before but all good now, so easy to install just be careful with the wires.

Using it for 6 months now. No problems at all.Worth every penny.It does what it says.It prints equally to original part.
