CCTREE 12V 40W 620 Ceramic Cartridge Heater and NTC Thermistor 100K 3950 for 3D Printer Creality CR-10 CR-10S S4 S5 Makerbot RepRap Prusa i3 (Pack of 10pcs)

I thought about going with a more expensive heater cartridge, but there is safety in numbers even if these aren't as good of quality. It has performed up to my standards and even came with a new thermistor to replace the old worn one. Good deal for the money.

Finally had to switch out the original cart in my cr10s after almost a year, swapped the the thermistor as well since the iron was already hot, both swap ins worked. Temp is pretty accurate at least from what I can tell from my prints and knowing the filament. Ramp up time is the same as the original or it is an amount to small for me to notice.The new cart and themistor have about 200 hours on em so far and no issues, and its nice to know if I do have issues I have 4 backups.

First thermistor was DOA, but everything else is fine. Can’t really complain due to the price and it got me up and running within 2 days.

these are perfect for my custom 3d printer

These cartridge bodies ARE NOT 6mm! This caused me to overtighten my Micro Swiss block screws and break one off. Besides, they aren't terminated on the PCB side. I was willing to overlook that, but being they won't even fit, this product gets 0 stars. I kept the thermistors, they possibly may work.

This product did what it was advertised to do. The Quality is good. My only objection to this product is that it is Made in China. I am SICK of putting MY Money into the pockets of a Communist, Godless, and Paganistic country who uses Slaves to Manufacture their products.

Old cartridge wires broke after a long time and had to swap it out. Took about 15minutes to swap out the cartridge and thermistor, including the extra time to reconnect the thermistor in the correct position.It's about 4" shorter than the original wire, but that should only be an issue for max height prints.

good
