Saved my printer!

My original heater broke mid-print. These arrived quickly and were easy to install even for a beginner. Highly recommend keeping a set handy.

Excellent backup parts

Bought these as spares. Tested one on a bench power supply and it reached target temp in seconds. Very satisfied with the build quality.

Perfect replacement for my Ender 3

These heating rods fit perfectly and heat up quickly. The NTC3950 sensor reads temperature accurately compared to my old one. Great value for the price.

Does the job

No complaints so far. My printer is back up and running. The thermistor calibration was spot on right out of the box.

Good quality, fast shipping

Works well on my 24V setup. Installation was straightforward. One star off because the wire insulation felt slightly thinner than expected, but it holds up under heat.
